    Ujian Alexander-Govern merupakan ujian kesamaan sukatan memusat yang teguh pada keadaan varians heterogen. Malangnya ujian ini tidak teguh pada keadaan data tidak normal. Adaptasi penganggar teguh seperti penganggar M satu langkah terubah suai (MOM) sebagai sukatan memusat menggantikan min didapati berupaya meningkatkan keteguhan ujian ini apabila dijalankan pada data terpencong. Penganggar ini mempunyai kelebihan berbanding min kerana tidak dipengaruhi oleh data yang tidak normal. Kajian ini mendapati bahawa ujian Alexander-Govern yang telah diubah suai ini berupaya mengawal Ralat Jenis I dengan baik pada data terpencong untuk semua keadaan. Kadar Ralat Jenis I yang dihasilkan kebanyakannya berada di dalam selang kriteria teguh ketat (0.045 hingga 0.055) pada aras keertian 0.05. Berbeza dengan kaedah pengujian asal yang mana pada kebanyakan keadaan, ujian teguh tetapi hanya dengan kriteria liberal (0.025 hingga 0.075), malahan ada kedaan yang mana ujian tidak teguh. Prestasi kaedah yang diubah suai ini juga setanding dengan keadah asal pada keadaan data normal. Kajian ini juga membandingkan kaedah Alexander Govern yang diubah suai dengan kaedah pengujian klasik seperti ujian-t dan ANO VA dan menyaksikan bahawa kaedah klasik tidak teguh pada keadaan varians heterogen.

    Susceptibility status of Aedes aegypti (L.) and Aedes albopictus Skuse larvae obtained from 12 states in Malaysia were evaluated against five insect growth regulators (IGRs), namely, pyriproxyfen, methoprene, diflubenzuron, cyromazine, and novaluron under laboratory conditions. Field populations of Ae. aegypti exhibited moderate resistance toward methoprene and low resistance toward pyriproxyfen, with resistance ratios of 12.7 and 1.4, respectively, but susceptibility to diflubenzuron, cyromazine, and novaluron. On the other hand, field populations of Ae. albopictus exhibited low resistance against diflubenzuron and novaluron, with resistance ratio of 2.1 and 1.0, respectively, but susceptibility to other tested IGRs. Our study concluded that the tested IGRs provide promising results and can be used to control field population of Ae. aegypti and Ae. albopictus, especially cyromazine. The use of IGR should be considered as an alternative when larvae develop resistance to conventional insecticides.

    Pengecaman senjata api semakin serius dan amat penting di dalam bidang penyiasatan jenayah khususnya untuk tempoh dua dekad ini. Dalam makalah ini, suatu sistem untuk pengecaman senjata api berasaskan tapak kelongsong peluru telah diperkenalkan. Tapak kelongsong peluru adalah satu daripada penunjuk yang amat penting dalam membantu menyelesaikan masalah pengecaman pistol. Peluru yang telah digunakan akan meninggalkan lebih daripada 30 ciri yang amat berharga pada tapak kelongsong bagi membantu pihak tertentu mengecam pistol yang telah diguna. Ciri-ciri tersebut sebagai suatu gabungan membentuk apa yang dikenali sebagai kesan cap jari bagi pistol. Lantaran itu, kajian ini adalah untuk mendapatkan fitur yang sesuai bagi pengecaman senjata api. Terlebih dahulu imej tapak kelongsong peluru ini telah ditemberengkan kepada tiga bahagian, membentuk tiga set imej yang berlainan. Imej-imej ini juga dilakukan prapemprosesan untuk membentuk tiga set imej lagi. Fitur-fitur seterusnya disaring daripada imej asal tapak kelongsong peluru dan imej yang telah melalui prapemprosesan. Dua puluh fitur yang berbeza secara signifikan telah diperoleh dan dikirakan untuk imej-imej asal dan yang telah dilakukan prapemprosesan. Kesemua pemprosesan telah dilakukan menggunakan pengaturcaraan MATLAB. Suatu skim berdasarkan analisis korelasi seterusnya telah diperkenalkan untuk pencarian fitur berdasarkan konsep meminimumkan lewahan data tetapi memastikan ciri-ciri unik tersimpan. Fitur-fitur yang berkorelasi tinggi akan digugurkan pasangannya dan hasilnya tinggal cuma tujuh fitur sahaja. Ketujuh-tujuh fitur ini telah diuji sebagai suatu vektor fitur untuk mengelaskan lima pistol daripada model yang sama menggunakan analisis diskriminan. Hasil pengelasan menunjukkan lebih 80% daripada imej-imej tapak kelongsong peluru itu telah dikelaskan dengan jayanya.

    Thyroid hormones (THs) L-thyroxine and L-triiodothyronine, primarily known as metabolism regulators, are tyrosine-derived hormones produced by the thyroid gland. They play an essential role in normal central nervous system development and physiological function. By binding to nuclear receptors and modulating gene expression, THs influence neuronal migration, differentiation, myelination, synaptogenesis and neurogenesis in developing and adult brains. Any uncorrected THs supply deficiency in early life may result in irreversible neurological and motor deficits. The development and function of GABAergic neurons as well as glutamatergic transmission are also affected by THs. Though the underlying molecular mechanisms still remain unknown, the effects of THs on inhibitory and excitatory neurons may affect brain seizure activity. The enduring predisposition of the brain to generate epileptic seizures leads to a complex chronic brain disorder known as epilepsy. Pathologically, epilepsy may be accompanied by mitochondrial dysfunction, oxidative stress and eventually dysregulation of excitatory glutamatergic and inhibitory GABAergic neurotransmission. Based on the latest evidence on the association between THs and epilepsy, we hypothesize that THs abnormalities may contribute to the pathogenesis of epilepsy. We also review gender differences and the presumed underlying mechanisms through which TH abnormalities may affect epilepsy here.

    INTRODUCTION: Topical corticosteroid phobia is a common phenomenon that can result in poor treatment adherence and therapeutic failure.

    OBJECTIVES: This study aims to evaluate the prevalence and degree of topical corticosteroid phobia and its impact on treatment adherence in various dermatological conditions. Additionally, we explored the sources of information regarding topical corticosteroids.

    MATERIALS AND METHODS: A cross-sectional study was conducted among 300 participants with topical corticosteroid usage experience. Topical corticosteroid phobia was assessed with the topical corticosteroid phobia (TOPICOP) scale, and treatment adherence was measured with the Elaboration d'un outil d'evaluation de l'observance des traitements medicamenteux (ECOB) score. Information sources regarding topical corticosteroids were identified, and their level of trust was assessed. The data were collected via questionnaires in three languages, namely English, Malay and Mandarin.

    RESULTS: The study found that topical corticosteroid phobia was prevalent, with 98% of participants expressing a certain degree of phobia. The mean global TOPICOP score was 32.7 ± 6.7%. The mean score of each domain was 27.1 ± 17.2% for knowledge and belief, 35.7 ± 23.8% for fears and 40.8 ± 25.8% for behaviour. Patients/caregivers who have eczema, highly educated, severe disease, low tolerability to symptoms, previous adverse effects with topical corticosteroids and tend to traditional/non-steroidal alternative therapy usage had a significant association with topical corticosteroid phobia (p<0.05). Dermatologists were the most common and trusted source of information on topical corticosteroids.

    CONCLUSIONS: This study highlights the widespread topical corticosteroid phobia in dermatological practice. Dermatologists should take the lead in combating steroid phobia and provide patients with public awareness regarding topical corticosteroids to improve treatment adherence and therapeutic outcomes.

    Gonadotropin-inhibitory hormone (GnIH) was first discovered in the Japanese quail, and peptides with a C-terminal LPXRFamide sequence, the signature protein structure defining GnIH orthologs, are well conserved across vertebrate species, including fish, reptiles, amphibians, avians, and mammals. In the mammalian brain, three RFamide-related proteins (RFRP-1, RFRP-2, RFRP-3 = GnIH) have been identified as orthologs to the avian GnIH. GnIH is found primarily in the hypothalamus of all vertebrate species, while its receptors are distributed throughout the brain including the hypothalamus and the pituitary. The primary role of GnIH as an inhibitor of gonadotropin-releasing hormone (GnRH) and pituitary gonadotropin release is well conserved in mammalian and non-mammalian species. Circadian rhythmicity of GnIH, regulated by light and seasons, can influence reproductive activity, mating behavior, aggressive behavior, and feeding behavior. There is a potential link between circadian rhythms of GnIH, anxiety-like behavior, sleep, stress, and infertility. Therefore, in this review, we highlight the functions of GnIH in biological rhythms, social behaviors, and reproductive and non-reproductive activities across a variety of mammalian and non-mammalian vertebrate species.

    OBJECTIVES: The clinical efficacy of corticosteroids remains unclear. The primary aim of this systematic review and meta-analysis was to evaluate the use of high-dose versus low- dose corticosteroids on the mortality rate of COVID-19 patients.

    DESIGN: Systematic review and meta-analysis.

    SETTING: Electronic search for randomized controlled trials and observational studies (MEDLINE, EMBASE, CENTRAL).

    PARTICIPANTS: Hospitalized adults ≥ 18 years old who were SARS-CoV-2 PCR positive.

    INTERVENTIONS: High-dose and low-dose corticosteroids.

    MEASUREMENTS AND MAIN RESULTS: A total of twelve studies (n=2759 patients) were included in this review. The pooled analysis demonstrated no significant difference in mortality rate between the high-dose and low-dose corticosteroids groups (n=2632; OR: 1.07 [95%CI 0.67, 1.72], p=0.77, I2=76%, trial sequential analysis=inconclusive). No significant differences were observed in the incidence of intensive care unit (ICU) admission rate (n=1544; OR: 0.77[95%CI 0.43, 1.37], p=0.37, I2= 72%), duration of hospital stay (n=1615; MD: 0.53[95%CI -1.36, 2.41], p=0.58, I2=87%), respiratory support (n=1694; OR: 1.51[95%CI 0.77, 2.96], p=0.23, I2=84%), duration of mechanical ventilation (n=419; MD: -1.44[95%CI -4.27, 1.40], p=0.32, I2=93%), incidence of hyperglycemia (n=516, OR: 0.91[95%CI 0.58, 1.43], p=0.68, I2=0%) and infection rate (n=1485, OR: 0.86[95%CI 0.64, 1.16], p=0.33, I2=29%).

    CONCLUSION: The meta-analysis demonstrated high-dose corticosteroids did not reduce mortality rate. However, high-dose corticosteroids did not pose higher risk of hyperglycemia and infection rate for COVID-19 patients. Due to the inconclusive trial sequential analysis, substantial heterogeneity and low level of evidence, future large-scale randomized clinical trials are warranted to improve the certainty of evidence for the use of high-dose compared to low-dose corticosteroids in COVID-19 patients.

    OBJECTIVES: With no clear end for the outbreak, identifying the drugs that are effective in COVID-19's management is of utmost importance to reduce the impact on the general population and the healthcare systems.

    METHODS: This is a systematic review and a meta-analysis evaluating the evidence from clinical trials on the effect of colchicine and corticosteroids against COVID-19. In this review, we have systematically searched five databases [(PubMed, Embase, clinicaltrials.gov, ICTRP, CINAHL (EBSCO)]. Cochrane's data extraction sheet was used to collect the required information, and RevMan-5.4.1 was used to conduct the meta-analysis and to assess the risk of bias. The review was registered in Prospero (CRD42022299718).

    RESULTS: The total number of included studies was 17, with 18,956 participants; the majority were male 12,001. Out of which, 8772 participants were on colchicine, 569 took methylprednisolone, and 64 patients received prednisolone. The meta-analysis has shown that colchicine had no significant effect on reducing the mortality rate among COVID-19 patients [OR 0.98(95% CI 0.90-1.08), p = .70), I2:1%)], corticosteroids have significantly reduced the mortality rates [OR 0.55 (95% CI 0.33-0.91), p = .02, I2:40]. Colchicine did not reduce the incidence of ICU admissions [OR 0.74 (95% CI 0.39-1.40), p = .35, I2:0%], while steroidal drugs significantly reduced the ICU admissions [OR 0.42 (95% CI 0.23-0.78), p = .005, I2:0%]. Unlike steroidal drugs [OR 0.53 (95% CI 0.30-0.95), p = .03, I2:61%], colchicine failed to reduce the need for mechanical ventilation [OR 0.73 (95% CI 0.48-1.10), p = .13, I2:76%]. Steroidal drugs significantly reduced the duration of hospitalization among COVID-19 patients [OR -0.50 (95% CI -0.79-0.21), p = .0007, I2:36%].

    CONCLUSIONS: The use of colchicine did not significantly reduce the mortality rate, ICU admissions, and mechanical ventilation among COVID-19 patients. Conversely, corticosteroids significantly reduced the mortality rate, ICU admissions, mechanical ventilation, and hospitalization duration among COVID-19 patients.

    BACKGROUND: Few studies have examined the impact of Coronavirus disease 2019 (COVID-19) infection on children with chronic lung disease (CLD).

    OBJECTIVE: To perform a systematic review and meta-analysis to determine the prevalence, risk factors for contracting COVID-19, and complications of COVID-19, in children with CLD.

    METHODS: This systematic review was based on articles published between January 1, 2020 and July 25, 2022. Children under 18 years old, with any CLD and infected with COVID-19 were included.

    RESULTS: Ten articles involving children with asthma and four involving children with cystic fibrosis (CF) were included in the analyses. The prevalence of COVID-19 in children with asthma varied between 0.14% and 19.1%. The use of inhaled corticosteroids (ICS) was associated with reduced risk for COVID-19 (risk ratio [RR]: 0.60, 95% confidence interval [CI]: 0.40-0.90). Uncontrolled asthma, younger age, AND moderate-severe asthma were not significant risk factors for contracting COVID-19. Children with asthma had an increased risk for hospitalization (RR: 1.62, 95% CI: 1.07-2.45) but were not more likely to require assisted ventilation (RR: 0.51, 95% CI: 0.14-1.90). The risk of COVID-19 infection among children with CF was <1%. Posttransplant and cystic fibrosis-related diabetes mellitus (CFRDM) patients were at an increased risk for hospitalization and intensive care treatment.

    CONCLUSION: Hospitalizations were higher in children with asthma with COVID-19 infection. However, using ICS reduced the risk of COVID-19 infection. As for CF, postlung transplantation and CFRDM were risk factors for severe disease.

    Colorectal cancer (CRC) is one of the most deaths causing diseases worldwide. Several risk factors including hormones like insulin and insulin like growth factors (e.g., IGF-1) have been considered responsible for growth and progression of colon cancer. Though there is a huge advancement in the available screening as well as treatment techniques for CRC. There is no significant decrease in the mortality of cancer patients. Moreover, the current treatment approaches for CRC are associated with serious challenges like drug resistance and cancer re-growth. Given the severity of the disease, there is an urgent need for novel therapeutic agents with ideal characteristics. Several pieces of evidence suggested that natural products, specifically medicinal plants, and derived phytochemicals may serve as potential sources for novel drug discovery for various diseases including cancer. On the other hand, cancer cells like colon cancer require a high basal level of reactive oxygen species (ROS) to maintain its own cellular functions. However, excess production of intracellular ROS leads to cancer cell death via disturbing cellular redox homeostasis. Therefore, medicinal plants and derived phytocompounds that can enhance the intracellular ROS and induce apoptotic cell death in cancer cells via modulating various molecular targets including IGF-1 could be potential therapeutic agents. Alkaloids form a major class of such phytoconstituents that can play a key role in cancer prevention. Moreover, several preclinical and clinical studies have also evidenced that these compounds show potent anti-colon cancer effects and exhibit negligible toxicity towards the normal cells. Hence, the present evidence-based study aimed to provide an update on various alkaloids that have been reported to induce ROS-mediated apoptosis in colon cancer cells via targeting various cellular components including hormones and growth factors, which play a role in metastasis, angiogenesis, proliferation, and invasion. This study also provides an individual account on each such alkaloid that underwent clinical trials either alone or in combination with other clinical drugs. In addition, various classes of phytochemicals that induce ROS-mediated cell death in different kinds of cancers including colon cancer are discussed.

    BACKGROUND: Chronic rhinosinusitis, with or without nasal polyps, can have a major impact on a person's quality of life. Treatment is usually conservative and may include nasal saline, intranasal corticosteroids, antibiotics or systemic corticosteroids. If these treatments fail endoscopic sinus surgery can be considered. During surgery, visibility of the surgical field is important for the identification of important anatomic landmarks and structures that contribute to safety. Impaired visualisation can lead to complications during surgery, inability to complete the operation or a longer duration of surgery. Different methods are used to decrease intraoperative bleeding, including induced hypotension, topical or systemic vasoconstrictors or total intravenous anaesthesia. Another option is tranexamic acid, an antifibrinolytic agent, which can be administered topically or intravenously.

    OBJECTIVES: To assess the effects of peri-operative tranexamic acid versus no therapy or placebo on operative parameters in patients with chronic rhinosinusitis (with or without nasal polyps) who are undergoing functional endoscopic sinus surgery (FESS).

    SEARCH METHODS: The Cochrane ENT Information Specialist searched the Cochrane ENT Trials Register; Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE; Ovid Embase; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 10 February 2022.

    SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing intravenous, oral or topical tranexamic acid with no therapy or placebo in the treatment of patients (adults and children) with chronic rhinosinusitis, with or without nasal polyps, undergoing FESS.

    DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. Primary outcome measures were surgical field bleeding score (e.g. Wormald or Boezaart grading system), intraoperative blood loss and significant adverse effects (seizures or thromboembolism within 12 weeks of surgery). Secondary outcomes were duration of surgery, incomplete surgery, surgical complications and postoperative bleeding (placing of packing or revision surgery) in the first two weeks after surgery. We performed subgroup analyses for methods of administration, different dosages, different forms of anaesthesia, use of thromboembolic prophylaxis and children versus adults. We evaluated each included study for risk of bias and used GRADE to assess the certainty of the evidence.

    MAIN RESULTS: We included 14 studies in the review, with a total of 942 participants. Sample sizes in the included studies ranged from 10 to 170. All but two studies included adult patients (≥ 18 years). Two studies included children. Most studies had more male patients (range 46.6% to 80%). All studies were placebo-controlled and four studies had three treatment arms. Three studies investigated topical tranexamic acid; the other studies reported the use of intravenous tranexamic acid. For our primary outcome, surgical field bleeding score measured with the Boezaart or Wormald grading score, we pooled data from 13 studies. The pooled result demonstrated that tranexamic acid probably reduces the surgical field bleeding score, with a standardised mean difference (SMD) of -0.87 (95% confidence interval (CI) -1.23 to -0.51; 13 studies, 772 participants; moderate-certainty evidence). A SMD below -0.70 represents a large effect (in either direction). Tranexamic acid may result in a slight reduction in blood loss during surgery compared to placebo with a mean difference (MD) of -70.32 mL (95% CI -92.28 to -48.35 mL; 12 studies, 802 participants; low-certainty evidence). Tranexamic acid probably has little to no effect on the development of significant adverse events (seizures or thromboembolism) within 24 hours of surgery, with no events in either group and a risk difference (RD) of 0.00 (95% CI -0.02 to 0.02; 8 studies, 664 participants; moderate-certainty evidence). However, there were no studies reporting significant adverse event data with a longer duration of follow-up. Tranexamic acid probably results in little difference in the duration of surgery with a MD of -13.04 minutes (95% CI -19.27 to -6.81; 10 studies, 666 participants; moderate-certainty evidence). Tranexamic acid probably results in little to no difference in the incidence of incomplete surgery, with no events in either group and a RD of 0.00 (95% CI -0.09 to 0.09; 2 studies, 58 participants; moderate-certainty evidence) and likely results in little to no difference in surgical complications, again with no events in either group and a RD of 0.00 (95% CI -0.09 to 0.09; 2 studies, 58 participants; moderate-certainty evidence), although these numbers are too small to draw robust conclusions. Tranexamic acid may result in little to no difference in the likelihood of postoperative bleeding (placement of packing or revision surgery within three days of surgery) (RD -0.01, 95% CI -0.04 to 0.02; 6 studies, 404 participants; low-certainty evidence). There were no studies with longer follow-up.

    AUTHORS' CONCLUSIONS: There is moderate-certainty evidence to support the beneficial value of topical or intravenous tranexamic acid during endoscopic sinus surgery with respect to surgical field bleeding score. Low- to moderate-certainty evidence suggests a slight decrease in total blood loss during surgery and duration of surgery. Whilst there is moderate-certainty evidence that tranexamic acid does not lead to more immediate significant adverse events compared to placebo, there is no evidence regarding the risk of serious adverse events more than 24 hours after surgery. There is low-certainty evidence that tranexamic acid may not change postoperative bleeding. There is not enough evidence available to draw robust conclusions about incomplete surgery or surgical complications.

    PURPOSE: Tocilizumab has shown equivocal outcomes in reducing mortality in COVID-19. The corticosteroids appear to be an affordable alternative to tocilizumab. This study aims to estimate the efficacy of tocilizumab and the corticosteroids particularly dexamethasone and methylprednisolone and to identify possible determinants of their efficacy.

    METHODS: Five electronic databases were searched for studies involving tocilizumab, dexamethasone, and methylprednisolone in treating COVID-19. We included case-control and randomized or partially randomized trials. Meta-regression for patient baseline characteristics, co-medications, and tocilizumab dose regimens was performed to identify contributing factors to drug efficacy.

    RESULTS: Thirteen randomized controlled trials (RCTs) and twenty-four case-control studies were included in our meta-analysis involving 18,702 patients. Meta-analysis among the RCTs showed that a summary estimate favoring mortality reduction (OR 0.71, 95%CI 0.55 - 0.92) contributed mainly by tocilizumab and dexamethasone. Among case-control studies, meta-analysis showed mortality reduction (OR 0.52, 95%CI 0.36 - 0.75) contributed by tocilizumab and tocilizumab-methylprednisolone combination. Methylprednisolone alone did not reduce mortality except for one study involving high dose pulse therapy. Meta-analysis also found that all three drugs did not significantly reduce mechanical ventilation (OR 0.72, 95%CI 0.32 - 1.60).

    CONCLUSION: Tocilizumab and dexamethasone emerge as viable options in reducing mortality in severe COVID-19 patients. A tocilizumab-corticosteroid combination strategy may improve therapeutic outcome in cases where single therapy fails.

    Bronchial asthma is an inflammatory disease of the airways manifested physiologically by a widespread narrowing of the air passages. Being an inflammatory disease of the airways, the most effective treatment available for the management of bronchial asthma are anti-inflammatory agents such as corticosteroids. However, it is known that at higher dosage levels, even inhaled corticosteroids have harmful systemic side-effects. Hence, justification of use of high-dose of inhaled corticosteroids can only be made if patients with severe asthma can be accurately identified. For this precise reason, methods have been devised to categorize asthma severity through various National Asthma Management Guidelines. The present guidelines predominantly stress on symptoms and lung functions as the yardstick for determining the severity of asthma attacks and parameters determining airway inflammation have not yet been incorporated into them. However, these guidelines have proved to be fairly accurate in determining asthma severity and in guiding the treatment in these patients and all healthcare personnel are strongly advised to follow them. It is hoped that future guidelines may incorporate measures of inflammation as well, in order to further improve the diagnostic and treatment modalities in these patients.

    CASE REPORT: Five cases of Kimura's disease had been treated in our centre from year 2003 to 2010. All cases were presented with head and neck mass with cervical lymphadenopathy. Surgical excision was performed for all cases. Definite diagnosis was made by histopathological examination of the resected specimens. One out of five cases developed tumour recurrence four years after resection.

    CONCLUSION: Surgical excision is our choice of treatment because the outcome is immediate and definite tissue diagnosis is feasible after resection. Oral corticosteroid could be considered as an option in advanced disease. However, tumour recurrence is common after cessation of steroid therapy.

    Nephrogenic diabetes insipidus (NDI), which can be congenital or acquired, results from the failure of the kidney to respond to the anti-diuretic hormone (ADH). This will lead to excessive water loss from the body in the form of urine. The kidney, therefore, has a crucial role in maintaining water balance and it is vital to restore this function in an artificial kidney. Herein, an ultrasensitive and highly selective aptameric graphene-based field-effect transistor (GFET) sensor for ADH detection was developed by directly immobilizing ADH-specific aptamer on a surface-modified suspended graphene channel. This direct immobilization of aptamer on the graphene surface is an attempt to mimic the functionality of collecting tube V 2 receptors in the ADH biosensor. This aptamer was then used as a probe to capture ADH peptide at the sensing area which leads to changes in the concentration of charge carriers in the graphene channel. The biosensor shows a significant increment in the relative change of current ratio from 5.76 to 22.60 with the increase of ADH concentration ranging from 10 ag/mL to 1 pg/mL. The ADH biosensor thus exhibits a sensitivity of 50.00 µA· ( g / mL ) - 1 with a limit of detection as low as 3.55 ag/mL. In specificity analysis, the ADH biosensor demonstrated a higher current value which is 338.64 µA for ADH-spiked in phosphate-buffered saline (PBS) and 557.89 µA for ADH-spiked in human serum in comparison with other biomolecules tested. This experimental evidence shows that the ADH biosensor is ultrasensitive and highly selective towards ADH in PBS buffer and ADH-spiked in human serum.
