Abstract
This study aimed to develop the Fenugreek seed mucilage-based pH-responsive hydrogel system in order to improve the oral bioavailability of methotrexate (MTX). Fenugreek seed mucilage (FSM) was extracted from Trigonella foenum-graecum seeds. F1-F9 formulations of pH-responsive hydrogels were prepared using various FSM ratios, methacrylic acid (MAA), and methylene bis acrylamide (MBA) via free radical polymerization technique. Swelling behavior and in vitro drug release studies of prepared hydrogels were evaluated. Toxicity studies of prepared hydrogels were performed on normal cells and on Wistar rats (n = 6). Moreover, in vivo pharmacokinetics parameters were studied on albino rabbits. Hydrogels formation was confirmed by FTIR analysis, thermal analysis and SEM studies. The maximum swelling of hydrogel was found to be 384.7% at pH 7.4. MTX-loaded hydrogel showed the controlled release of MTX up to 24 h following Super Case II transport. Prepared hydrogels exhibited no toxicity in normal cells as well as in experimental subjects. MTX loaded hydrogels exhibited less inhibition compared to free MTX on Hela cells. In Vivo studies revealed 7.5-fold improved oral bioavailability of MTX with higher Cmax (928 ng/mL). These results indicate that the pH-responsive hydrogel system based on FSM is a promising tool for the controlled delivery of MTX.

Abstract
Recent studies demonstrating a higher incidence of metabolic disorders after calving have challenged the management practice of increasing dietary energy density during the last ~3 wk prepartum. Despite our knowledge at the whole-animal level, the tissue-level mechanisms that are altered in response to feeding management prepartum remain unclear. Our hypothesis was that prepartum body condition score (BCS), in combination with feeding management, plays a central role in the peripartum changes associated with energy balance and inflammatory state. Twenty-eight mid-lactation grazing dairy cows of mixed age and breed were randomly allocated to 1 of 4 treatment groups in a 2 × 2 factorial arrangement: 2 prepartum BCS categories (4.0 and 5.0, based on a 10-point scale; BCS4, BCS5) obtained via differential feeding management during late-lactation, and 2 levels of energy intake during the 3 wk preceding calving (75 and 125% of estimated requirements). Subcutaneous adipose tissue was harvested via biopsy at -1, 1, and 4 wk relative to parturition. Quantitative polymerase chain reaction was used to measure mRNA and microRNA (miRNA) expression of targets related to fatty acid metabolism (lipogenesis, lipolysis), adipokine synthesis, and inflammation. Both prepartum BCS and feeding management had a significant effect on mRNA and miRNA expression throughout the peripartum period. Overfed BCS5 cows had the greatest prepartum expression of fatty acid synthase (FASN) and an overall greater expression of leptin (LEP); BCS5 was also associated with greater overall adiponectin (ADIPOQ) and peroxisome proliferator-activated receptor gamma (PPARG), whereas overfeeding upregulated expression of proadipogenic miRNA. Higher postpartum expression of chemokine ligand 5 (CCL5) and the cytokines interleukin 6 (IL6) and tumor necrosis factor (TNF) was detected in overfed BCS5 cows. Feed-restricted BCS4 cows had the highest overall interleukin 1 (IL1B) expression. Prepartum feed restriction resulted in greater chemokine ligand 2 (CCL2) expression. Overall, changes in mRNA expression were consistent with the expression pattern of inflammation-related miRNA. These data shed light on molecular mechanisms underlying the effect of prepartum BCS and feeding management on metabolic and inflammatory status of adipose tissue during the peripartum period. Data support the use of a controlled feed restriction prepartum in optimally conditioned cows, as well as the use of a higher level of dietary energy in under-conditioned cows.

Abstract
BACKGROUND Perinatal depression has been linked with deleterious child development outcomes, yet maternal depression interventions have not been shown to have lasting effects on child development, and evidence is not available from countries of low or middle income. In the Thinking Healthy Programme cluster-randomised controlled trial, a perinatal depression intervention was assessed in Pakistan in 2006-07. The intervention significantly reduced depression levels 12 months post partum compared with a control. We aimed to assess the effect of this same intervention on the cognitive, socioemotional, and physical development of children at around age 7 years. METHODS Mother-child dyads who participated in the Thinking Healthy Programme cluster-randomised controlled trial were interviewed when the index child was about 7 years old. A reference group of 300 mothers who did not have prenatal depression and, therefore, did not receive the original intervention, was enrolled with their children at the same time. The primary cognitive outcome was the score on the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV); primary socioemotional outcomes included scores on the Strengths and Difficulties Questionnaire (SDQ) and the Spence Children's Anxiety Scale (SCAS); and primary physical outcomes were height-for-age, weight-for-age, and body-mass index (BMI)-for-age Z scores. Generalised linear modelling with random effects to account for clustering was the main method of analysis. Analyses were by intention to treat. The Thinking Healthy Programme cluster-randomised trial was registered at ISRCTN.com, number ISRCTN65316374. FINDINGS Of 705 participating mother-child dyads interviewed at the end of the Thinking Healthy Programme randomised controlled trial, 584 (83%) dyads were enrolled. 289 mothers had received the intervention and 295 had received a control consisting of enhanced usual care. The mean age of the children was 7·6 years (SD 0·1). Overall, cognitive, socioemotional, or physical development outcomes did not differ between children in the intervention or control groups whose mothers had prenatal depression. When compared with the reference group of children whose mothers did not have prenatal depression, the Thinking Healthy Programme trial children had worse socioemotional outcomes; mean scores were significantly higher on the SDQ for total difficulty (11·34 vs 10·35; mean difference 0·78, 95% CI 0·09-1·47; p=0·03) and on the SCAS for anxiety (21·33 vs 17·57; mean difference 2·93, 1·15-4·71; p=0·0013). Cognitive and physical outcomes did not differ. INTERPRETATION Our findings show that cognitive, socioemotional, and physical developmental outcomes of children at age 7 years whose mother had prenatal depression did not differ between those who received the Thinking Healthy Programme intervention and those who received the control. Further investigation is needed to understand what types of complex interventions or approaches are needed for long-term gains in maternal and child wellbeing. Prolonged, detailed, and frequent follow-up is warranted for all interventions. FUNDING Grand Challenges Canada (Government of Canada), Saving Brains programme.

Abstract
Two hundred and three consecutive cases of prolonged labour have been retrospectively reviewed from January 1984 to December 1986. The incidence of prolonged labour was 4.39%. It was noted that 66.5% of the patients with prolonged labour were unbooked emergency admissions, and 73.3% were primipara. The causes of prolonged labour were the occipitoposterior position (10.8%), relative cephalopelvie disproportion (18.2%), uterine dysfunction (44.5%), and in 26.1% an obstructive cause was present. A spontaneous vaginal delivery occurred in 34.4%, a forceps delivery in 22.6% and the caesarean section rate was 29%. The maternal mortality, febrile and non-febrile morbidity were 9.7 per 1000 total births, 42.8% and 17.2% respectively, which showed a direct relation to the duration of labour, and a significant increase in the patients with obstructed labour, and after an abdominal delivery. The corrected perinatal mortality was 165 per 1000 total births, which was also directly related to the duration of labour, and 74.3% of the perinatal deaths occurred in the patients with obstructed labour. The perinatal mortality in the study group was nearly three times higher than the overall hospital group. Neonatal morbidity occurred in 48.8% of the newborns.
