    Brain ischemia is among the leading cause of death with majority of the cases are associated with ischemic strokes. It can occur in two forms of either focal or global ischemia. Neurodegenerative disorder such as Alzheimer and Parkinson diseases is also on the rise worldwide. These disorders have common similarities; i.e. they all affecting the central nervous system with debilitating effect to the patient. In this review, we look into the promising role of flavonoids, a natural bioactive compound found abundant in vegetables, fruits and traditional herbs. Treatment with flavonoids such as curcumin, lycopene, ginsenoside, vitexin and baicalin have shown promising neuroprotective effects against ischemic-induced injury. Besides anticancer, antioxidant and immunomodulation properties, flavonoid also exerts neuroprotective effects by increases neuronal viability, increases tissue perfusion and cerebral blood flow and reduce ischemic-related apoptosis. In addition, flavonoid also exerts anti-amyloidogenic effect and reduces loss of dopaminergic neurons in the brain. These results suggesting flavonoids might be able to serve as a potential therapeutic agent in brain disorders.

    Attention deficit hyperactive disorder (ADHD), a hyperactivity disorder prevalent among children may continue as an adulthood attention deficit. To date, treating an individual with an adult ADHD may be an arduous task as it involves numerous challenges, which include a need for high index of suspicion to diagnose this medical condition. Many psychiatric disorders masquerade as ADHD and delay the necessary assessment and proper treatment for this debilitating medical disorder. Adult ADHD is often misdiagnosed (or under diagnosed) due to the fact that this medical condition is being masked by the patients' high level of intellectual achievement. As the ADHD in adult persists, it may end-up with impairment in the personal-social-occupational function in which the management becomes a great challenge. The treatment of ADHD can be optimized by using various drugs targets agents like norepinephrine-dopamine reuptake inhibitor (NDRI), with or without psycho stimulants like methylphenidate, which is marketed as Ritalin. Bupropion, an NDRI has a novel effect on ADHD as the molecule exerts its effects by modulating the reward-pleasure mesolimbic dopaminergic system and at the same time regulates the elevating mood dimension of the noradrenergic neurotransmission. The role of Bupropion in the neural and psychopharmacological perspective treatment of ADHD was deliberated. The present review highlights the novel effects of Bupropion in ADHD treatment, together with the help of other successful bio-psycho-social measures. This may be of immense benefit to the psychiatrists for treating their patients.

    Osteoporosis is posing a tremendous healthcare problem globally. Much effort has been invested in finding novel antiosteoporotic agents to stop the progression of this disease. Tocotrienol, one of the isoforms of vitamin E, is poised as a potential antiosteoporotic agent. Previous studies showed that tocotrienol as a single isomer or as a mixture demonstrated both anabolic and antiresorptive effects in various rodent models of osteoporosis. In vitro experiments further demonstrated that tocotrienol could up-regulate genes related to osteoblastogenesis and modify receptor activator of nuclear factor kappa B signaling against osteoclastogenesis. Additionally, tocotrienol was also shown to be a strong 3- hydroxy-3-methyl-glutaryl-CoA reductase down-regulator with a mechanism different from that of statins. Inhibition of the mevalonate pathway affects both osteoblast and osteoclast formation in favor of the former. Tocopherol, a more commonly used isoform of vitamin E does not possess similar effects. Tocotrienol is also a potent antioxidant. It can scavenge free radicals and prevent oxidative damage on osteoblast thus promoting its survival. It may also up-regulate the antioxidant defense network in osteoclast and indirectly act against free radical signaling essential in osteoclastogenesis. The effects of tocotrienol on Wnt/β-catenin signaling essential in osteoblastogenesis have not been determined. More mechanistic studies need to be conducted to illustrate the antiosteoporotic effects of tocotrienol. Clinical trials are also required to confirm its effects in humans. In conclusion, tocotrienol demonstrates great potential as an antiosteoporotic agent and much research effort should be invested to develop it as an agent to curb osteoporosis.

    Skeletal tissue undergoes continuous remodeling which makes it unique among other body tissues. Osteoporosis is a common bone metabolic disorder affecting both men and women. Osteoporosis and its complications mainly osteoporotic fractures, have a high impact on health and economy. Current approved medications are associated with numerous side effects, which limit their use. Identification of a new and safe therapy is mandatory. Statins, also known as HMGCoA reductase inhibitors, are frequently used for the treatment of hypercholesterolemia and for the prevention of morbidity and mortality associated with cardiovascular disease. Statins improved bone health status in intact and ovariectomised rodents following high clinically intolerable oral doses. However, this beneficial effect of statins could not be significantly demonstrated in humans. The reason behind this discrepancy might be due to the safety and bioavailability of the currently used oral statins. Vitamin E, especially the tocotrienols at the dose 60 mg/kg/day provided significant antiosteoporotic effects in different animal models of osteoporosis. The use of the aforementioned dose of tocotrienols was shown to be safe in both humans and animals. Enhancement of bone formation and reduction of bone resorption were achieved more effectively by a combination of tocotrienols and statins than by either treatment when supplemented separately at clinically tolerable doses. Therefore, the adverse effects associated with high statin doses might be avoided with the coadministration of tocotrienols. Moreover, the combination therapy strategy might be useful for patients who are at high risk of osteoporosis, cardiovascular events and hypercholesterolaemia.

    Nicotine is one of the most abused substances worldwide and can cause several harmful effects on health. One of the harmful effects, which is often ignored, is osteoporosis. Smoking has been shown to cause a decrease in bone mineral density in humans. Animal studies have proven that nicotine exerts negative effects on bone. The number of people who smoke increases each day. Those who smoke start at a very young age and they usually smoke for years. This will increase the risk of developing osteoporosis. As the prevalence of osteoporosis increases, the risk of fractures also increases. The major concerns are disability following fractures, mortality due to complications after fractures and the increasing cost of management and therapy. This paper will review the effects of nicotine on bone and the potential natural products which can be used as treatment for nicotine-induced osteoporosis.

    Osteoporosis is a metabolic bone disorder that affects both men and women worldwide. It causes low bone mass and therefore increases bone susceptibility to fracture when bone undergoes a minor trauma. Lack of estrogen is the principal cause of osteoporosis. Estrogen, calcium, calcitonin, vitamin D and several antioxidants help in the prevention of osteoporosis. In order to effectively treat osteoporosis, there has been an extended research on the biological activities of traditional medicines since synthetic medicines possess several side effects that reduce their efficacy. Therefore, there is a need to develop new treatment alternatives for osteoporosis. This review centres on the scientific researches carried out on the evaluation of Chinese traditional medicines in the treatment of osteoporosis. Various plants like Achyranthes bidentata, Davallia formosana, polygonatum sibiricum, Cibotium barometz, Er-Zhi-Wan, Curculigo orchioides and a combined treatment of Hachimi-jio-gan (Ba-Wei-Di-Huang-Wan) with alendronate proved active in preventing post-menopausal osteoporosis.

    Osteoporosis may cause bone fracture even under slight trauma. Osteoporotic fracture has become a major public health problem but until today, the treatments available are not satisfactory. Many pre-clinical testings on animals were done to find new agents that can be sourced from natural products and synthetic drugs for osteoporotic fracture healing. Animal models are more appropriate for fracture healing study than human subject due to several reasons including the ethical issues involved. The bones of rodents are similar to human in term of their morphological change and response to therapy. Small rodents such as rats and mice are suitable animal models for fracture healing studies as they have a similar bone remodeling system to human. To date, there is no specific guideline to carry out fracture healing studies in animal models for the evaluation of new agents. This paper highlights the protocols of various fracture and fixation methods for experimental osteoporotic fracture healing using rodent models.

    Fracture healing is a process of recovering injured bone tissue forms and functions. Osteoporosis can delay the healing process, which contributes to personal suffering and loss of activities. Osteoporosis patients tend to lose bone mass at the metaphyseal region which require treatment to increase bone mass. Postmenopausal osteoporosis is the most common osteoporosis that occurs in women which subsequently resulted in fractures even under slight trauma. Estrogen Replacement Therapy (ERT), the recommended therapy for postmenopausal osteoporosis, is associated with higher risk of breast cancer, ovarian cancer and cardiovascular diseases. As osteoporotic fractures are becoming a public health issue, alternative treatment is now being thoroughly explored. The potential agent is statins, the HMG-CoA reductase inhibitor which is widely used for hypercholesterolemia treatment. Statins have been found to increase bone mass by stimulation of Bone morphogenetic protein-2 (BMP-2) expression and Vascular Endothelial Growth Factor (VEGF) production. However, these bone forming effects were achieved at very high systemic doses. Therefore, studies on locally applied statins are required to further explore the ability of statins to stimulate bone formation at acceptable doses for better fracture healing. This review highlights the animal and clinical studies on fracture healing promotions by statins and the mechanisms involved.

    Bone quality assessment is important in assessments of potential agents for the prevention and treatment of osteoporosis. Bone density, microarchitecture and strength are important determinants in osteoporotic study which are widely studied using Dual-Energy X-ray Absorptiometry (DXA), histomorphometry and radiological imaging techniques. In recent years, high resolution micro-CT has become feasible for in vitro or in vivo evaluation of bone architecture. Three-dimensional images of micro-CT reflected high correlations with the conventional histomorphometry and DXA. In comparison to other imaging techniques, micro-CT is the most effective tool in detecting early bone changes for fracture prediction and assessments of potential anti-osteoporotic agents. It is crucial to define an ideal setting with safe radiation doses and appropriate methods for image reconstruction and segmentation to obtain high resolution images. Micro-CT evaluation provides a better insight of bone structure as well as non-metric parameters such as connectivity density, structural model index (SMI) and degree of anisotropy (DA). This non- invasive imaging technique is also equipped with finite element analysis for evaluation of bone biomechanical strength. Micro-CT allows a compressive understanding of the relationships between bone density, microarchitecture and strength which is fundamental to development of pharmacological interventions.

    Psychotic disorders are recognized as severe mental disorders that rigorously affect patient's personality, critical thinking, and perceptional ability. High prevalence, global dissemination and limitations of conventional pharmacological approaches compel a significant burden to the patient, medical professionals and the healthcare system. To date, numerous orally administered therapies are available for the management of depressive disorders, schizophrenia, anxiety, bipolar disorders and autism spectrum problems. However, poor water solubility, erratic oral absorption, extensive first-pass metabolism, low oral bioavailability and short half-lives are the major factors which limit the pharmaceutical significance and therapeutic feasibility of these agents. In recent decades, nanotechnology-based delivery systems have gained remarkable attention of the researchers to mitigate the pharmaceutical issues related to the antipsychotic therapies and to optimize their oral drug delivery, therapeutic outcomes, and patient compliance. Therefore, the present review was aimed to summarize the available in vitro and in vivo evidences signifying the pharmaceutical importance of the advanced delivery systems in improving the aqueous solubility, transmembrane permeability, oral bioavailability and therapeutic outcome of the antipsychotic agents.

    BACKGROUND: Eurycoma longifolia is a well-documented herbal medicine that has gained widespread recognition due to its versatile pharmacological activities including anticancer, antimalarial, antimicrobial, antioxidant, aphrodisiac, anti-inflammatory, anxiolytic, anti-diabetic, antirheumatism and anti-ulcer. Plethora of in vitro and in vivo studies evidenced their excellent antiproliferative and anticancer efficacy against various types of human cancers.

    OBJECTIVE: This review was aimed to critically analyze the therapeutic viability and anticancer efficacy of Eurycoma longifolia in the treatment of cancer and also to propose its molecular and translational mechanism of cytotoxicity against cancerous cells.

    RESULTS: Among a range of medicinally active compounds isolated from various parts (roots, stem, bark and leaves) of Eurycoma longifolia, 16 compounds have shown promising anti-proliferative and anticancer efficacies. Eurycomanone, one of the most active medicinal compounds of Eurycoma longifolia, displayed a strong dose-dependent anticancer efficacy against lung carcinoma (A-549 cells) and breast cancer (MCF-7 cells); however, showed moderate efficacy against gastric (MGC-803 cells) and intestinal carcinomas (HT-29 cells). The prime mode of cytotoxicity of Eurycoma longifolia and its medicinal compounds is the induction of apoptosis (programmed cell death) via the up-regulation of the expression of p53 (tumor suppressor protein) and pro-apoptotic protein (Bax) and downregulation of the expression of anti-apoptotic protein (Bcl-2). A remarkable alleviation in the mRNA expression of various cancer-associated biomarkers including heterogeneous nuclear ribonucleoprotein (hnRNP), prohibitin (PHB), annexin-1 (ANX1) and endoplasmic reticulum protein-28 (ERp28) has also been evidenced.

    CONCLUSION: Eurycoma longifolia and its medicinal constituents exhibit promising anticancer efficacy and thus can be considered as potential complementary therapy for the treatment of various types of human cancers.

    BACKGROUND: Eurycoma longifolia (E. longifolia) has gained widespread recognition due to its versatile pharmacological activities including aphrodisiac, anticancer, antimicrobial, antioxidant, anti-inflammatory, anxiolytic, anti-diabetic, ergogenic, insecticidal, anti-rheumatism, bone protection, and anti-ulcer effects.

    OBJECTIVE: This review was aimed to critically overview the literature and summarizes the antibacterial, antiprotozoal, and antifungal trends of E. longifolia and its medicinally active components.

    RESULTS: Besides its well-documented safety, efficacy, and tolerability, a plethora of in vitro, in vivo, and human clinical studies has evidenced the antimicrobial efficacy of E. longifolia and its bioactive constituents. Phytochemical screening of various types of extracts (methanolic, ethyl acetate, and nbutanolic) from different parts (roots, stem, and leaves) of E. longifolia displayed a dose-dependent antibacterial, antiprotozoal, and antifungal responses. Comparative analysis revealed that the root extract of E. longifolia exhibited the highest antimicrobial efficacy compared to other parts of the plant. Bioactivity-guided fractionation identified that among all of the medicinal compounds isolated/ extracted from different parts of E. longifolia, eurycomanone displayed the strongest antibacterial, antiprotozoal and antifungal activities.

    CONCLUSION: Based on the critical analysis of the literature, we identified that E. longifolia exhibits promising antibacterial, antiprotozoal, and antifungal efficacies against various pathogenic microbes and thus can be considered as a potential complementary and alternative antimicrobial therapy.

    Cancer patients are commonly associated with various physical and psychological symptoms. In palliative setting, the aims are to relieve those symptoms, improve quality of life, and increase medication adherence among cancer patients. Antidepressants are generally accepted for the treatment of depression among patients with or without cancer. Some other potential benefits of the antidepressants have been reported in cancer patients.

    OBJECTIVE: This study aims to review the use of antidepressants for physical and psychological symptoms in cancer patients.

    RESULTS: Our findings showed the mixed result of positive and negative findings in various symptoms associated with cancer patients. These studies are categorised according to the hierarchy of evidence from high to low level, namely randomised controlled trials, cohort studies, case-control studies, case series, case reports, as well as other type of publications. The majority of antidepressants used in cancer patients seem to be beneficial for the treatment of depression, anxiety, hot flashes and other symptoms such as sexual dysfunction, fatigue, nicotine dependence, vasomotor symptoms, executive functions, sleep problems, pruritus, as well as for hypochondriasis. While fluoxetine was found to be associated with the reduction of antiemetic property in ondansetron, mirtazapine was identified to be a good alternative in treating nausea and cachexia among cancer patients.

    CONCLUSION: More research studies with adequate statistical power are warranted to validate the use of antidepressants among cancer patients in treating these physical and psychological symptoms.

    BACKGROUND: Vortioxetine is a multimodal antidepressant that has been developed for the treatment of major depressive and anxiety disorders. The aim of this review is to quantitatively synthesize all data of the efficacy, safety and tolerability of Vortioxetine in treating anxiety disorder.

    METHOD: Terms of "Vortioxetine" OR "LuAA21004" AND "anxiety" OR "fear" OR "panic" OR "phobia" were searched. A total of two phase II and five phase III clinical trials were found.

    RESULTS: Vortioxetine was overall superior to placebo in terms of the mean change from baseline in HAM-A total score at week 8 with the pool effect size of -2.95, 95% CIs, -4.37 to -1.53, p<0.01. The patients who received 5 mg of Vortioxetine had higher response rate when compared to placebo (pooled odds ratio=1.4, 95% CI = 1.08 to 1.82, p=0.01). However, the pooled odds ratio of the HAMA remission rate was not statistically significant for both Vortioxetine and placebo (pooled odds ratio= 1.06, 95% CI = 0.86 to 1.30, p=0.62). Although the discontinuation due to adverse effects was higher in Vortioxetine than placebo group (pooled OR= 1.55, 95% CI = 1.04 to 2.31, P= 0.037), the lack of efficacy (pooled OR= 0.39, 95% CI = 0.27 to 0.57, P<0.01) was higher in placebo than Vortioxetine group. Most of the adverse effects were mild and moderate. Overall, Vortioxetine displayed a good safety and tolerability profile.

    CONCLUSION: This review supports the use of Vortioxetine for anxiety disorder. However, further longterm placebo-control observational study or a post market survey would help in strengthening the evidence for this treatment modality.

    Colorectal cancer (CRC) remains one of the major leading causes of cancer related morbidity and mortality. Apart from the conventional anti-neoplastic agents, metformin, a biguanide anti-diabetic agent, has recently found to have anti-cancer property. Several studies observed the effect of metformin towards its anti-cancer effect on colon or colorectal cancer in diabetic patients. However, only a few studies showed its effect on colorectal cancer in relation to the non-diabetic status. The present review aimed to highlight the insight into the molecular pathway of metformin towards colorectal cancer in the absence of diabetes mellitus. In CRC-independent of diabetes mellitus, highly deregulation of PI3K/AKT pathway is found which activates the downstream mammalian target of rapamycin (mTOR). Metformin inhibits cancer growth in colon by suppressing the colonic epithelial proliferation by inhibiting the mTOR pathway. Metformin exerts its anti-neoplastic effects by acting on tumour suppressor pathway via activating the adenosine monophosphate.activated protein kinase (AMPK) signaling pathway. Metformin interrupts the glucose metabolism by activating the AMPK. Metformin reduces tumour cell growth and metastasis by activating the p53 tumour suppressor gene. In addition to its therapeutic benefits, metformin is easily accessible, cost effective with better tolerance to the patients compared to the chemotherapeutic agents. This review summarised modern findings on the therapeutic applications of metformin on the colorectal cancer with no evidences of diabetes mellitus.

    Preventing osteoporotic fractures in millions of individuals may significantly reduce the associated morbidity and health-care expenditures incurred. As such, the search for newer anti-osteoporotic agents has been ongoing for years. Genetic studies have proven that the secreted protein sclerostin is one of the main culprits, which negatively regulates the bone formation. Recently, sclerostin-neutralizing monoclonal antibodies (Scl-Ab) in rodent studies have shown positive effects on bone homeostasis. An extensive search of the literature was performed in the BIOSIS, Cinahl, EMBASE, Pub- Med, Web of Science and Cochrane Library databases to evaluate the published murine studies on the effects of Scl-Ab on the bone metabolism and histomorphometric parameters. Our systematic review depicts a significant association between Scl-Ab administration and improvement in bone formation, bone density, bone volume and trabecular thickness.

    BACKGROUND: Age-related macular degeneration (AMD) is a condition that accounts for 75% of cases of legal blindness in individuals over the age of 50.

    OBJECTIVES: The objective of this review has been to evaluate the clinical effectiveness of available combined treatments modalities in the treatment of neovascular AMD.

    DATA SOURCES: Central and Medline were searched for original research studies (Phase I, II, III), abstracts, and review articles concerning combination therapies for the control of neovascular AMD. We included randomized controlled trials (RCTs).

    RESULTS: The results of therapeutic trials focused on the actual options in the management of neovascular AMD are discussed. Intravitreal treatment with substances targeting all isotypes of vascular endothelial growth factor (VEGF) results in a significant increase in visual acuity in patients with neovascular AMD. The combination with occlusive therapies like verteporfin photodynamic therapy (V-PDT) potentially offers a reduction of re-treatment frequency rate and long-term maintenance of the benefit reached. Despite the promise from combining anti-VEGF therapies with V-PDT, other combinations to improve outcomes with V-PDT deserve attention. Corticosteroids demonstrated an antiangiogenic effect and targeted the extravascular components of CNV, such as inflammatory cells and fibrocytes. Nevertheless, the study on the clinical application of corticosteroids will require a better understanding of the potential complications. Further developments interacting with various steps in the angiogenic cascade are under clinical or preclinical evaluation and may soon become available. In AMD the goal of a combination regimen is to address the therapy toward neovascular, inflammatory, and proliferative components of the disease.

    CONCLUSIONS: Combined treatments strategies are an obvious step providing disease control when it is not achieved with a single therapeutic approach. One risk of using a single therapy to control AMD is a rebound induced by compensatory stimulation of other pathogenetic pathways. Combination therapy is a logical approach to address mechanisms of disease progression that appear to be self-sustaining once initiated.

    BACKGROUND: Normal pressure hydrocephalus (NPH) is a critical brain disorder in which excess cerebrospinal fluid (CSF) is accumulated in the brain's ventricles causing damage or disruption of the brain tissues. Amongst various signs and symptoms, difficulty in walking, blurred speech, impaired decision making and critical thinking, and loss of bladder and bowl control are considered the hallmark features of NPH.

    OBJECTIVE: The current review was aimed to present a comprehensive overview and critical appraisal of majorly employed neuroimaging techniques for rational diagnosis and effective monitoring of effectiveness of employed therapeutic intervention for NPH. Moreover, a critical overview of recent developments and utilization of pharmacological agents for treatment of hydrocephalus has also been appraised.

    RESULTS: Considering the complications associated with the shunt-based surgical operations, consistent monitoring of shunting via neuroimaging techniques hold greater clinical significance. Despite having extensive applicability of MRI and CT scan, these conventional neuroimaging techniques are associated with misdiagnosis or several health risks to patients. Recent advances in MRI (i.e., Sagittal-MRI, coronal-MRI, Time-SLIP (time-spatial-labeling-inversion-pulse), PC-MRI and diffusion-tensor-imaging (DTI)) have shown promising applicability in diagnosis of NPH. Having associated with several adverse effects with surgical interventions, non-invasive approaches (pharmacological agents) have earned greater interest of scientists, medical professional, and healthcare providers. Amongst pharmacological agents, diuretics, isosorbide, osmotic agents, carbonic anhydrase inhibitors, glucocorticoids, NSAIDs, digoxin, and gold-198 have been employed for management of NPH and prevention of secondary sensory/intellectual complications.

    CONCLUSION: Employment of rational diagnostic tool and therapeutic modalities avoids misleading diagnosis and sophisticated management of hydrocephalus by efficient reduction of cerebrospinal fluid (CSF) production, reduction of fibrotic and inflammatory cascades secondary to meningitis and hemorrhage, and protection of brain from further deterioration.
