Diabetes mellitus is a disorder accompanied by oxidative and inflammatory responses, that might exacerbate vascular complications. The purpose of this study was to investigate the potential antioxidant and anti-inflammatory effects of melatonin (MLN) on streptozotocin (STZ)-induced diabetic rats subjected to middle cerebral artery occlusion followed by reperfusion (MCAO/Re).

Diabetes was induced in rats by a single injection of STZ (55 mg/kg; i.p.). The cerebral injury was then induced by MCAO/Re after six weeks. After 24 h of MCAO/Re the MLN (10 mg/kg) was administered orally for 14 days. Serum and tissue samples were extracted to determine malondialdehyde (MDA), reduced glutathione (GSH), nitric oxide (NO), interleukin-1β (IL-1β), and the tumor necrosis factor- α (TNF-α). Part of the brain tissue was kept in formalin for pathological and immunohistochemical studies to determine nuclear factor kappa B (NF-kB) and cyclooxygenase-2 (COX-2) immune reactivity.

MCAO/Re in STZ-induced hyperglycaemic rats caused a decrease in brain GSH, an increase in brain MDA, and NO was increased in both serum and brain tissue. Rats showed a prominent increase in the serum and brain inflammatory markers

. IL-1β and TNF-α. Oral treatment with MLN (10 mg/kg) for two weeks reduced the brain levels of MDA, NO, IL-1β, and TNF-α. Impressive amelioration in pathological findings, as well as a significant decrease in NF-kB and COX2 immune stained cells of the cerebral cortex, hippocampus, and cerebellum, occurred after treatment with MLN. It also succeeded to suppress the exacerbation of damage in the brain of hyperglycaemic rats.

Daily intake of MLN attenuates the exacerbation of cerebral ischemic injury in a diabetic state.

To investigate the pharmacokinetics of piperine after single oral doses of capsules containing Sahastara (SHT) remedy dried ethanolic extracts in healthy Thai volunteers.

Twenty-four healthy volunteers were divided into two dosage groups. They received a single oral dose of SHT remedy extract capsules of 100 or 200 mg. Blood was collected at time intervals of 0, 0.5, 1, 2, 4, 6, 8, 12, 24, and 48 h. Acute clinical safety was monitored by complete physical examination and laboratory tests during the study period. Piperine concentration in blood and urine was determined by liquid chromatography tandem-mass spectrometry.

No serious adverse events were detected, only one volunteer had abdominal pain that was self-limiting. The pharmacokinetics of piperine following SHT remedy extract capsule administration demonstrated a mean peak concentration (C

) of piperine of 3.77 μg/mL and 6.59 μg/mL after dosing with 100 and 200 mg, respectively. Interestingly, a secondary maximum concentration of piperine was observed in this study, which might be related to enterohepatic recirculation. Negligible amounts of unchanged piperine were detected in urine.

The systemic exposure of piperine after SHT remedy ethanolic extract demonstrated dose proportionality after single oral dosing of 100-200 mg. Piperine was detectable in plasma for at least 48 h with evidence of enterohepatic recirculation. Metabolism and excretion profiles of piperine after administration of SHT remedy extract capsule need to be further explored for phytopharmaceutical product development.

Clinical information in Wegeda town showed that the prevalence of waterborne diseases was 58%. This study aimed to evaluate bacteriological and physicochemical drinking water quality in Wegeda town. This study will add valuable scientific data for future intervention. Water samples from protected and unprotected springs, hand-dug well, taps, and households’ containers were collected from November 2018 to June 2019 for bacteriological and physicochemical analyses. Besides, information about the potential risk factors was collected using a structured questionnaire. A total of 120 water samples were collected and analyzed for total and fecal coliform counts using the multiple tube fermentation method (MPN). The presence of Escherichia coli was also checked from fecal coliform positive samples collected from households’ containers. Selected physicochemical parameters were also determined using the standard methods. In allosal systems, and intensive health education and sanitation practices for the community are highly recommended.

Although proper management of electronic waste (e-waste) is key to preventing disease and protecting the environment, there is no clear mechanism for its management in Uganda. This study assessed knowledge, perceptions, and practices of e-waste management among consumers in Kampala city, Uganda.

We conducted a cross-sectional study among people who used, repaired, or sold electronics (consumers). Both quantitative and qualitative methods of data collection using a sequential explanatory strategy were utilized. The quantitative survey involved 640 study participants, while qualitative interviews included 18 key informant interviews with stakeholders and six focus group discussions with 57 consumers. Modified Poisson regression was used to establish associations with corresponding 95% confidence intervals, and qualitative data analysed thematically.

Two-thirds (67.7%; 433/640) of electronics consumers had poor knowledge on the management of e-waste. More than three-quarters 79.1% (506) of the consumers have positive perceptions. There is need for increased awareness on e-waste management to prevent its effects on health and the environment. Special attention should be towards sensitisation on e-waste handling practices before disposal and final disposal options available.

Ear infections in children often cause abnormal postural stability. However, the long-term effects of recurrent ear infections on postural stability have not been investigated.

The purpose of this study was to examine the long-term effects of multiple ear infections on pediatric postural stability.

Forty children aged 10-12 years were divided into two groups (18 participants with a history of tympanostomy tubes and/or 3 or more ear infections prior to age five and 22 participants without a history of tympanostomy tubes and/or 0-2 ear infections prior to age five). Computerized Stability Evaluation Test (SET) and noncomputerized postural stability were measured for all participants.

A significant difference was found in median postural stability scores in the SET during a tandem stance on an unstable surface between the two groups (median (minimum, maximum) of 9.1 (1.4, 11.4) versus 5.8 (1.7, 12.8),

= 0.04). In addition, there was a significant difference in median Pediatric Balance Scale scores between participants with versus without ear infection (54 (47, 56) versus 56 (55, 56),

= 0.001).

Results suggest that children ages 10-12 with a history of tympanostomy tubes and/or 3 or more ear infections prior to age five have decreased postural stability.

But, its utility is limited due to the high cost, expertise required, lack of portability, and restricted availability. Therefore, bioelectrical impedance analysis (BIA) has gained recognition in resource-limited settings for the measurement of body composition indices in the screening of children for childhood obesity. To determine whether BIA represents a viable alternative to DXA in the assessment of body composition in obese children in the community setting in Sri Lanka, the concordance between BIA and DXA was determined. Fat mass (FM), percentage fat mass (%FM), and fat-free mass (FFM) were measured in 97 obese children using DXA and BIA, and the concordance between the methods was analyzed using independent sample t-test, regression analysis, and Bland-Altman plots. Significant mean differences were observed between DXA and BIA in measuring FM and FFM. However, high correlations were seen in DXA- and BMI-derived FM and FFM measurements (FM r = 0.92 and FFM 0.83, P less then 0.001 for both). Compared to DXA, BIA overestimated FM and %FM and underestimated FFM. When compared with DXA-derived measurements, the accuracy errors (SEE) of BIA for FM, FFM, and %FM were relatively higher in boys (3.56 kg, 4.49 kg, and 5.46%, respectively) than in girls (2.44 kg, 3.72 kg, and 3.5%), respectively. BA plots showed a systematic error in the measurements of FM, FFM, and %FM in both sexes. Despite the limitations inherited, BIA is a viable alternative to DXA for the measurement of body composition in obese children of 5-15 yrs. The accuracy errors observed, however, need to be taken into consideration when interpreting results at the individual level.

Schistosomiasis caused by

parasites is one of the most common parasitic infections worldwide. Genetic regulation of the genus

, which has different developmental stages throughout its life, is quite complex. In these parasites, thousands of long noncoding RNAs (lncRNAs) estimated to be functional were identified. Identifying the transcripts expressed in common and detecting their functions for better understanding of the role of these lncRNAs require a comparative study.

Assembled RNA-seq datasets belonging to

and

were obtained from the National Center for Biotechnology. A basic local alignment search tool (BLASTN) analysis was conducted against previously constructed lncRNA library to identify the common lncRNAs between two species. LncRNAs target genes and their gene ontology annotation was performed.

In

and

, 5132 and 3589 lncRNA transcripts were detected, respectively. These two species had 694 lncRNAs in common. A significant number of lncRNAs was determined to be transcribed from sex chromosomes. The frequently expressed lncRNAs appear to be involved in metabolic and biological regulation processes.

These two species share similar lncRNAs; thus, this finding is a clue that they might have similar functions. In sexual development, they especially might play important roles. Our results will provide important clues to further studies about interactions between human hosts and parasites and the infection mechanisms of

parasites.
