Fulltext Tree shrew lavatories: a novel nitrogen sequestration strategy in a tropical pitcher plant

Clarke CM, Bauer U, Lee CC, Tuen AA, Rembold K, Moran JA

Biol Lett, 2009 Oct 23;5(5):632-5.
PMID: 19515656 DOI: 10.1098/rsbl.2009.0311

Nepenthes pitcher plants are typically carnivorous, producing pitchers with varying combinations of epicuticular wax crystals, viscoelastic fluids and slippery peristomes to trap arthropod prey, especially ants. However, ant densities are low in tropical montane habitats, thereby limiting the potential benefits of the carnivorous syndrome. Nepenthes lowii, a montane species from Borneo, produces two types of pitchers that differ greatly in form and function. Pitchers produced by immature plants conform to the 'typical' Nepenthes pattern, catching arthropod prey. However, pitchers produced by mature N. lowii plants lack the features associated with carnivory and are instead visited by tree shrews, which defaecate into them after feeding on exudates that accumulate on the pitcher lid. We tested the hypothesis that tree shrew faeces represent a significant nitrogen (N) source for N. lowii, finding that it accounts for between 57 and 100 per cent of foliar N in mature N. lowii plants. Thus, N. lowii employs a diversified N sequestration strategy, gaining access to a N source that is not available to sympatric congeners. The interaction between N. lowii and tree shrews appears to be a mutualism based on the exchange of food sources that are scarce in their montane habitat.

Fulltext Lactobacillus plantarum DR7 Modulated Bowel Movement and Gut Microbiota Associated with Dopamine and Serotonin Pathways in Stressed Adults

Liu G, Chong HX, Chung FY, Li Y, Liong MT

Int J Mol Sci, 2020 Jun 29;21(13).
PMID: 32610495 DOI: 10.3390/ijms21134608

We have previously reported that the administration of Lactobacillus plantarum DR7 for 12 weeks reduced stress and anxiety in stressed adults as compared to the placebo group, in association with changes along the brain neurotransmitters pathways of serotonin and dopamine-norepinephrine. We now aim to evaluate the effects of DR7 on gut functions, gut microbiota compositional changes, and determine the correlations between microbiota changes and the pathways of brain neurotransmitters. The administration of DR7 prevented an increase of defecation frequency over 12 weeks as compared to the placebo (p = 0.044), modulating the increase of stress-induced bowel movement. Over 12 weeks, alpha diversity of gut microbiota was higher in DR7 than the placebo group across class (p = 0.005) and order (p = 0.018) levels, while beta diversity differed between groups at class and order levels (p < 0.001). Differences in specific bacterial groups were identified, showing consistency at different taxonomic levels that survived multiplicity correction, along the phyla of Bacteroides and Firmicutes and along the classes of Deltaproteobacteria and Actinobacteria. Bacteroidetes, Bacteroidia, and Bacteroidales which were reduced in abundance in the placebo group showed opposing correlation with gene expression of dopamine beta hydrolase (DBH, dopamine pathway; p < 0.001), while Bacteroidia and Bacteroidales showed correlation with tryptophan hydroxylase-II (TPH2, serotonin pathway; p = 0.001). A correlation was observed between DBH and Firmicutes (p = 0.002), Clostridia (p < 0.001), Clostridiales (p = 0.001), Blautia (p < 0.001), and Romboutsia (p < 0.001), which were increased in abundance in the placebo group. Blautia was also associated with TDO (p = 0.001), whereas Romboutsia had an opposing correlation with TPH2 (p < 0.001). Deltaproteobacteria and Desulfovibrionales which were decreased in abundance in the placebo group showed opposing correlation with DBH (p = 0.001), whereas Bilophila was associated with TPH2 (p = 0.001). Our present data showed that physiological changes induced by L. plantarum DR7 could be associated with changes in specific taxa of the gut microbiota along the serotonin and dopamine pathways.

Guzman Rojas R, Kamisan Atan I, Shek KL, Dietz HP

Int Urogynecol J, 2016 Jun;27(6):939-44.
PMID: 26670577 DOI: 10.1007/s00192-015-2914-3

INTRODUCTION AND HYPOTHESIS: Symptoms of obstructive defecation (OD) are common in women. Transperineal ultrasound (TPUS) has been used for the evaluation of defecatory disorders. The aim of our study was to determine the overall prevalence of anatomical abnormalities of the posterior compartment and their correlations with OD in women seen in a tertiary urogynecology clinic.
METHODS: This is a retrospective study on 750 women seen at a tertiary urogynecological unit who had undergone a standardized interview, clinical examination, and 4D TPUS. Univariate and multivariate logistic regression analyses were undertaken to study the association between examination findings and symptoms of OD. This study was approved by the local human research ethics committee (Nepean Blue Mountains Local Health District Human Research Ethics Committee, IRB approval no. 13-16).
RESULTS: The datasets of 719 women were analyzed. Mean age was 56.1 (18.4-87.6) years. Ninety-seven patients (13 %) reported fecal incontinence, 190 (26 %) constipation, and 461 (64 %) symptoms of OD. On examination, 405 women (56 %) were diagnosed with significant posterior compartment prolapse (POP-Q ≥ stage 2), which was associated with symptoms of OD (p

Retention marker excretion suggests incomplete digesta mixing across the order primates

Matsuda I, Espinosa-Gómez FC, Ortmann S, Sha JCM, Osman I, Nijboer J, et al.

Physiol Behav, 2019 09 01;208:112558.
PMID: 31125579 DOI: 10.1016/j.physbeh.2019.112558

The digestive tract of animals, and the patterns how passage markers are excreted from them, have been fruitfully compared to chemical reactor models from engineering science. An important characteristic of idealized reactor models is the smoothness of the curves plotting marker concentrations in outflow (i.e., faeces) over time, which is the result of the assumed complete mixing of the marker with the reactor contents. Published excretion patterns from passage experiments in non-primate mammals appear to indicate a high degree of digesta mixing. In order to assess whether marker excretion graphs from primates differ from ideal outflow graphs, we performed passage experiments in eight individuals of three foregut-fermenting species (Pygathrix nemaeus, Trachypithecus auratus and Semnopithecus vetulus), and added them to available marker excretion curves from the literature. In the resulting collection, 23 out of a total of 25 patterns in foregut fermenters (21 individuals of 10 species from 7 studies), and 13 out of 15 in hindgut fermenters (9 individuals of 2 species from 2 studies), showed an irregular, 'spiky' pattern. We consider this proportion to be too high to be explained by experimental errors, and suggest that this may indicate a taxon-wide characteristic of particularly incomplete digesta mixing, acknowledging that further data from less related primate species are required for corroboration. Our hypothesis is in accordance with previous findings of a comparatively low degree of 'digesta washing' (differential retention of particulate and fluid digesta) in primates. Together with literature findings that suggest a low chewing efficiency in primates compared to other mammals, these observations indicate that in contrast to other herbivores, the success of the primate order is not derived from particularly elaborate adaptations of their ingestive and digestive physiology.

Functional uniqueness of a small carnivore as seed dispersal agents: a case study of the common palm civets in the Tabin Wildlife Reserve, Sabah, Malaysia

Nakashima Y, Inoue E, Inoue-Murayama M, Abd Sukor JR

Oecologia, 2010 Nov;164(3):721-30.
PMID: 20602116 DOI: 10.1007/s00442-010-1714-1

Many carnivorous mammals consume fruits and disperse the intact seeds to specific sites. Few studies have attempted to quantify this seed dispersal or evaluate its effectiveness, despite its potential importance and functional uniqueness. In the study reported here, we found that a frugivorous carnivore, the common palm civet (Paradoxurus hermaphroditus), generated seed shadows that are distinct from those of the sympatric frugivore, the pig-tailed macaque (Macaca nemestrina), and played a unique and important role in the regeneration of Leea aculeata (Leeaceae). We found that macaques dispersed the seeds randomly, while civets dispersed them non-randomly to sites such as the banks of small rivers, rain-flow paths, abandoned trails, and treefall gaps, which are characterized by low stem density and canopy cover. Seeds of L. aculeata that were dispersed by civets to the banks of rivers and gaps had significantly higher survival and growth rates than those dispersed to rain-flow paths or abandoned trails. Seeds dispersed by macaques or to random locations also had low survival. Although the effects of the civets on seed fate were not straightforward, compared with macaques and random dispersal, civets significantly enhanced the survival and growth of L. aculeata seeds after 1 year. These results indicate that non-random dispersal by civets is important for the persistence of L. aculeata. Civets may disperse other plant species and thus could have profound effects on forest dynamics.

Intra- and interspecific agonistic behavior of the subterranean termite Microcerotermes crassus (Isoptera: Termitidae)

Wong N, Lee CY

J Econ Entomol, 2010 Oct;103(5):1754-60.
PMID: 21061976

The aim of our study was to investigate the intra- and interspecific agonistic behaviors exhibited by the worker and soldier castes of the subterranean termite Microcerotermes crassus Snyder (Isoptera: Termitidae). Aggression between M. crassus colonies from different field locations and also against three termite species--Coptotermes gestroi (Wasmann), Globitermnes sulphureus Haviland, and Odontotermes sp.--were observed in the laboratory. Termite responses were tested in paired combination of castes (soldiers versus soldiers, soldiers versus workers, and workers versus workers) consisting of 10 individuals each. Significant agonistic behaviors were observed only in encounters between pairings of different termite species. M. crassus was aggressive toward individuals from different species but not toward individuals from different M. crassus colonies. Mortality of M. crassus reached 100% in most of the interspecific encounters. However, no or low mortality was recorded in the intraspecific pairings.

Shaari MK, Tan YW, Abdullah MY, Sharudin MF, Osman M, Teoh THQ, et al.

J Pediatr Surg, 2024 Apr;59(4):571-576.
PMID: 38160189 DOI: 10.1016/j.jpedsurg.2023.12.002

BACKGROUND: Assessment of postoperative bowel function in anorectal malformation (ARM) patients is crucial for benchmarking outcomes. We compared existing bowel function scoring systems in various aspects in patients with ARM.
METHODS: With ethical approval, this was a cross-sectional study involving 5 paediatric surgery referral centres in Malaysia, comparing the Kelly, Japanese Study Group of Anorectal Anomalies (JSGA), Holschneider and Krickenbeck bowel function questionnaires. We recruited patients aged 4-17 years, who had completed definitive surgery & stoma closure (where relevant) > 12 months prior to participation. We standardised outcomes of each scoring system into categories ('good', 'fair', 'poor' and 'very poor') to facilitate comparison. Parents & patients were surveyed and asked to rate the ease of understanding of each questionnaire. The difference in protocol scores rated between parents and patients were compared. Association of each bowel function scoring protocol with type of anomaly was assessed. Statistical significance was p

Digitation associated with defecation: what does it mean in urogynaecological patients?

Hai-Ying C, Guzmán Rojas R, Hall JC, Atan IK, Dietz HP

Int Urogynecol J, 2016 Feb;27(2):229-32.
PMID: 26264476 DOI: 10.1007/s00192-015-2813-7

INTRODUCTION AND HYPOTHESIS: Obstructed defecation is a common symptom complex in urogynaecological patients, and perineal, vaginal and/or anal digitation may required for defecation. Translabial ultrasound can be used to assess anorectal anatomy, similar to defecation proctography. The aim of the present study was to determine the association between different forms of digitation (vaginal, perineal and anal) and abnormal posterior compartment anatomy.
METHODS: A total of 271 patients were analysed in a retrospective study utilising archived ultrasound volume datasets. Symptoms of obstructed defecation (straining at stool, incomplete bowel emptying, perineal, vaginal and anal digitation) were ascertained on interview. Postprocessing of stored 3D/4D translabial ultrasound datasets obtained on maximal Valsalva was used to diagnose descent of the rectal ampulla, rectocoele, enterocoele and rectal intussusception at a later date, blinded to all clinical data.
RESULTS: Digitation was reported by 39 % of our population. The position of the rectal ampulla on Valsalva was associated with perineal (p = 0.02) and vaginal (p = 0.02) digitation. The presence of a true rectocoele was significantly associated with perineal (p = 0.04) and anal (p = 0.03) digitation. Rectocoele depth was associated with all three forms of digitation (P = 0.005-0.02). The bother of symptoms of obstructed defecation was strongly associated with digitation (all P

Prevalence of irritable bowel syndrome in young adult Malaysians: a survey among medical students

Tan YM, Goh KL, Muhidayah R, Ooi CL, Salem O

J Gastroenterol Hepatol, 2003 Dec;18(12):1412-6.
PMID: 14675271 DOI: 10.1046/j.1440-1746.2003.03212.x

BACKGROUND AND AIMS: Irritable bowel syndrome (IBS) is a common functional bowel disease in the West. Information on the prevalence of IBS in the Asian population is relatively scanty. The aims of the present study were to determine the prevalence of IBS and to assess the symptom subgroups based on the predominant bowel habit in a young adult population of Asian origin.

METHODS: Basic demographic data and symptoms of IBS using the Rome I criteria were sought using a questionnaire administered to all apparently healthy students in a medical school. Other questions asked related to alcohol intake, smoking, chili consumption, dietary fiber intake, and to psychological and psychosomatic symptoms of anxiety, depression, insomnia, headache, and backache. The health-care seeking behavior of the subjects was also analyzed.

RESULTS: Of the 610 questionnaires administered, 533 complete responses were received (response rate of 87.4%). The responders comprised 229 men (43.0%) and 304 (57.0%) women with a mean age of 22 +/- 1.8 years. The ethnic distribution was Malays 278 (52.2%), Chinese 179 (33.6%), Indians 46 (8.6%), and others 30 (5.6%). Eighty-four (15.8%) reported symptoms consistent with the diagnosis of IBS, predominantly women. Sixty-five (77.4%) and six (7.1%) were of the constipation-predominant and diarrhea-predominant IBS subgroups, respectively. Thirteen (15.5%) subjects fell into the non-specific IBS subgroup. The self-reported psychological and psychosomatic symptoms of anxiety (P = 0.02), depression (P = 0.002), insomnia (P = 0.006), headache (P = 0.04), and backache (P = 0.006) were encountered more frequently in the subjects with IBS. Only 13.1% of the IBS group had consulted their health-care practitioner, and 20.2% reported self-medication.

CONCLUSIONS: Symptoms supportive of the diagnosis of IBS were common among young Malaysians, with a prevalence rate of 15.8%. There were significantly more women with IBS than men. Within the IBS population, the majority (77.4%) was of the constipation-predominant IBS subgroup. A significantly higher prevalence of psychological and psychosomatic symptoms was found in individuals with IBS. Only a minority sought medical advice for their symptoms.

Free radical scavenging, antidiarrheal and anthelmintic activity of Pistia stratiotes L. extracts and its phytochemical analysis

Bin Karim MF, Imam H, Sarker MM, Uddin N, Hasan N, Paul N, et al.

Pak J Pharm Sci, 2015 May;28(3):915-20.
PMID: 26004725

In this phyto-pharmacological screening of Pistia stratiotes L leaf and root extracts each separately in two different solvents demonstrated its potential medicinal value. Apparent antioxidant value is demonstrated by DPPH, Nitric oxide scavenging and Ferric ion reducing method. Additionally, total flavonoid and phenolic compounds were measured. The leaf methanolic extract scavenged both nitric oxide (NO) and DPPH radical with a dose dependent manner. But the pet ether fraction of root was found to have highest efficacy in Fe(3±) reducing power assay. Flavonoid was found to contain highest in the pet ether fraction of root (411.35mg/g) in terms of quercetin equivalent, similarly highest amount (34.96mg/g) of total phenolic compounds (assayed as gallic acid equivalents) were found to contain in the same fraction. The methanolic fractions appeared less cytotoxic compared to pet ether extracts. The plant extracts caused a dose dependent decrease in faecal droppings in both castor oil and magnesium sulphate induced diarrhea, where as leaf extracts in each solvent appeared most effective. Also, the plant extracts showed anthelmintic activity in earthworm by inducing paralysis and death in a dose dependent manner. At highest doses (50 mg/ml) all fractions were almost effective as the positive control piperazine citrate (10 mg/ml). Thus, besides this cytotoxic effect it's traditional claim for therapeutic use can never be overlooked.

Fulltext Effects of Synbiotics among Constipated Adults in Serdang, Selangor, Malaysia-A Randomised, Double-Blind, Placebo-Controlled Trial

Lim YJ, Jamaluddin R, Hazizi AS, Chieng JY

Nutrients, 2018 Jun 26;10(7).
PMID: 29949873 DOI: 10.3390/nu10070824

Synbiotics approach complementarily and synergistically toward the balance of gastrointestinal microbiota and improvement in bowel functions. A randomised, double-blind, placebo-controlled study was conducted to examine the effects of a synbiotics supplement among constipated adults. A total of 85 constipated adults, diagnosed by Rome III criteria for functional constipation were randomised to receive either synbiotics (n = 43) or placebo (n = 42) once daily (2.5 g) in the morning for 12 weeks. Eight times of follow-up was conducted every fortnightly with treatment response based on a questionnaire that included a record of evacuation (stool frequency, stool type according to Bristol Stool Form Scale), Patients Assessment on Constipation Symptoms (PAC-SYM), and Patients Assessment on Constipation Quality of Life (PAC-QOL). There were no significant differences in stool evacuation, but defecation frequency and stool type in treatment group were improved tremendously than in placebo group. While the treatment group was reported to have higher reduction in severity of functional constipation symptoms, the differences were not statistically significant. Dietary supplementation of synbiotics in this study suggested that the combination of probiotics and prebiotics improved the functional constipation symptoms and quality of life although not significant. This was due to the high placebo effect which synbiotics failed to demonstrate benefit over the controls.

Home-Based Transabdominal Interferential Electrical Stimulation for Six Months Improves Paediatric Slow Transit Constipation (STC)

Yik YI, Hutson J, Southwell B

Neuromodulation, 2018 Oct;21(7):676-681.
PMID: 29164818 DOI: 10.1111/ner.12734

BACKGROUND: Transcutaneous electrical stimulation (TES) for one to two months has produced some improvement in treatment-resistant slow-transit constipation (STC) in children. Optimal parameters for treatment are not known. It is possible that more improvement would occur with stimulation for longer. This study examined the effectiveness of stimulation for six months.
METHODS: Children with STC confirmed by nuclear transit study (NTS) were enrolled prospectively. All had chronic constipation for greater than two years and had failed medical treatment. TES was performed for one hour/day for six months using the INF 4160 (Fuji Dynamics) portable stimulator and 4 cm × 4 cm electrodes near the belly button and on the back. Families kept bowel diaries and completed PEDSQLCore QOL (4.0) questionnaires before and at end of treatment.
RESULTS: Sixty-two children (34 females; seven years, 2-16 year) with STC were studied. Defecation frequency increased in 57/62 (91%, mean ± SEM pre- 1.49 ± 0.20 vs. post- 3.25 ± 0.25 defecation/week, p

Fulltext Randomised clinical trial: mixed soluble/insoluble fibre vs. psyllium for chronic constipation

Erdogan A, Rao SS, Thiruvaiyaru D, Lee YY, Coss Adame E, Valestin J, et al.

Aliment Pharmacol Ther, 2016 07;44(1):35-44.
PMID: 27125883 DOI: 10.1111/apt.13647

BACKGROUND: Fibre supplements are useful, but whether a plum-derived mixed fibre that contains both soluble and insoluble fibre improves constipation is unknown.
AIM: To investigate the efficacy and tolerability of mixed soluble/insoluble fibre vs. psyllium in a randomized double-blind controlled trial.
METHODS: Constipated patients (Rome III) received mixed fibre or psyllium, 5 g b.d., for 4 weeks. Daily symptoms and stool habit were assessed using stool diary. Subjects with ≥1 complete spontaneous bowel movement/week above baseline for ≥2/4 weeks were considered responders. Secondary outcome measures included stool consistency, bowel satisfaction, straining, gas, bloating, taste, dissolvability and quality of life (QoL).
RESULTS: Seventy-two subjects (mixed fibre = 40; psyllium = 32) were enrolled and two from psyllium group withdrew. The mean complete spontaneous bowel movement/week increased with both mixed fibre (P < 0.0001) and psyllium (P = 0.0002) without group difference. There were 30 (75%) responders with mixed fibre and 24 (75%) with psyllium (P = 0.9). Stool consistency increased (P = 0.04), straining (P = 0.006) and bloating scores decreased (P = 0.02) without group differences. Significantly more patients reported improvement in flatulence (53% vs. 25%, P = 0.01) and felt that mixed fibre dissolved better (P = 0.02) compared to psyllium. QoL improved (P = 0.0125) with both treatments without group differences.
CONCLUSIONS: Mixed fibre and psyllium were equally efficacious in improving constipation and QoL. Mixed fibre was more effective in relieving flatulence, bloating and dissolved better. Mixed fibre is effective and well tolerated.

Fulltext Cannabis sativa subsp. sativa's pharmacological properties and health effects: A scoping review of current evidence

Lim XY, Tan TYC, Muhd Rosli SH, Sa'at MNF, Sirdar Ali S, Syed Mohamed AF

PLoS One, 2021;16(1):e0245471.
PMID: 33465140 DOI: 10.1371/journal.pone.0245471

INTRODUCTION: Hemp (Cannabis sativa subsp. sativa), commonly used for industrial purposes, is now being consumed by the public for various health promoting effects. As popularity of hemp research and claims of beneficial effects rises, a systematic collection of current scientific evidence on hemp's health effects and pharmacological properties is needed to guide future research, clinical, and policy decision making.
OBJECTIVE: To provide an overview and identify the present landscape of hemp research topics, trends, and gaps.
METHODS: A systematic search and analysis strategy according to the preferred reporting items for systematic review and meta-analysis-ScR (PRISMA-ScR) checklist on electronic databases including MEDLINE, OVID (OVFT, APC Journal Club, EBM Reviews), Cochrane Library Central and Clinicaltrials.gov was conducted to include and analyse hemp research articles from 2009 to 2019.
RESULTS: 65 primary articles (18 clinical, 47 pre-clinical) were reviewed. Several randomised controlled trials showed hempseed pills (in Traditional Chinese Medicine formulation MaZiRenWan) improving spontaneous bowel movement in functional constipation. There was also evidence suggesting benefits in cannabis dependence, epilepsy, and anxiety disorders. Pre-clinically, hemp derivatives showed potential anti-oxidative, anti-hypertensive, anti-inflammatory, anti-diabetic, anti-neuroinflammatory, anti-arthritic, anti-acne, and anti-microbial activities. Renal protective effects and estrogenic properties were also exhibited in vitro.
CONCLUSION: Current evidence on hemp-specific interventions are still preliminary, with limited high quality clinical evidence for any specific therapeutic indication. This is mainly due to the wide variation in test item formulation, as the multiple variants of this plant differ in their phytochemical and bioactive compounds. Future empirical research should focus on standardising the hemp plant for pharmaceutical use, and uniformity in experimental designs to strengthen the premise of using hemp in medicine.
