RESUMEN

INTRODUCTION: Polycystic Ovary Syndrome (PCOS) is an endocrine disorder which accounts for infertility around the world. The disease is characterized by elevated secretion of androgens in the women which results in enlargement of ovaries with accumulation of fluid filled cysts, irregular menstrual cycles, and hirsutism. This study reports the efficacy of a patented, standardized Trigonella foenum-graecum extract (Furocyst®) as an effective phytotherapeutic for effective management of PCOS. OBJECTIVE: This randomized one-arm study assessed the efficacy of Furocyst® in 107 female volunteers over a period of 12 consecutive weeks. METHOD: Following approvals of the Institutional Ethical Committee and clinicaltrials.gov, 107 female volunteers (age: 18-45 years) were recruited. Subjects consumed Furocyst® capsules (1,000 mg/day p.o.) over a period of 12 consecutive weeks. Physical (Sonographic scan, Hirsutism Score, Menstrual cycle, Body Weight, BMI, Height, Waist Circumference and Blood Pressure) and biochemical parameters (LH/FSH ratio, TSH, Prolactin, Fasting insulin, Fasting Glucose, triglyceride, cholesterol, HOMA Index, free and total testosterone, 2-hour GTT, DHEAS) were assessed at the beginning of the study as well as at intervals of 4 weeks till 12 weeks to determine the efficacy of Furocyst® on PCOS induced damage on reproductive and endocrine system. RESULTS: Furocyst® treatment induced >40% reduction of mean cyst sizes in both ovaries with corresponding reduction of in ovarian volumes. LH:FSH ratio was also significantly improved with corresponding reduction in total testosterone and prolactin levels. As a result of improvement in endocrine function, menstrual cycle became regular in the subjects. Furocyst® also reduced the severity of other associated ailments such as insulin resistance, dyslipidemia, and improved liver function significantly. CONCLUSIONS: This study reinstated the efficacy of Furocyst® as a safe phytotherapeutic to reverse the effects of PCOS inflicted damage on the female reproductive system without any adverse events.

RESUMEN

Purpose: Preeclampsia (PE) affects 5-7% of the pregnancies worldwide, and is one of the most dreaded disorders of pregnancy contributing to maternal and neonatal mortality. PE is mostly presented in the third trimester of pregnancy. Here, we used serum placental growth factor (PIGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) to develop a model for predicting PE in Indian women in early second trimester. Methods: In this case-control study, a total 1452 healthy pregnant women were recruited. Blood samples were collected at the following gestational weeks (GWs), 12-20 (GW1), 21-28 (GW2) and 29-term (GW3), and post-delivery. Body mass index (BMI) was calculated by anthropometric measurements. Serum sFlt-1, PIGF and VEGF were analyzed by ELISA. A predictive model for PE was developed using multivariable logistic regression analysis. Results: In PE cases, serum PlGF and VEGF levels were significantly lower at each GW, while serum sFlt-1 was lower only at GW1, relative to age-matched controls, (n = 132/group). Age-matched comparison between PE cases and controls indicated that sFlt-1 was associated with decreased PE outcome (Odds ratio. OR = 0.988, CI = 0.982-0.993), whereas sFlt-1/PlGF ratio (OR = 1.577, CI = 1.344-1.920) and BMI (OR = 1.334, CI = 1.187-1.520) were associated with increased PE outcome. Logistic regression was used to develop a predictive model for PE at GW1. Using testing dataset, model was externally validated which resulted in 88% accuracy in predicting PE cases at 0.5 probability cutoff. Conclusion: Prediction model using sFlt-1, sFlt-1/PlGF ratio and BMI may be useful to predict PE as early as 12-20 weeks in women with optimal sensitivity and specificity.

RESUMEN

Microplastics act as a potential vector for a wide range of contaminants, which have emerged as a major environmental hazard in the modern world. Considering the seriousness of the problem, a simulated laboratory and field experiment were conducted to study the weathering of pristine microplastics following long-term exposure to natural background radiation and the marine environment after being disposed of in the open environment. For the study, polyethylene-originating (HDPE and LDPE) microplastics were chosen. The study revealed that radiation exposure causes surface roughness and cracks, leading to an increased surface area, which can invite a wide spectrum of pollutants to sorb on their surface. Furthermore, we report that the radiation-induced morphological changes favor microbial colonization on the microplastic surface when exposed to the marine environment. The growth of biofilms on the surface of microplastics reduces their hydrophobicity, which may attract a wide variety of polar contaminants. The study led to an interesting finding: that the HDPE microplastic surface is more conducive for biofilm growth in comparison to the LDPE surface.

RESUMEN

Radioiodine is one of the long-lived fission products and also an important radionuclide released during nuclear accidents, which generates interest in its environmental fate. Its sorption has been studied in a wide range of materials, but no equivalent study exists for microplastics, an emerging environmental vector. Weathering and biofilm formation on microplastics can enhance radioiodine sorption. For the first time, we're reporting how radioiodine interacts with different types of polyethylene derived microplastics (pristine, irradiated, and biofilm developed microplastics). This study revealed that exposure to radiation and the marine environment significantly alters the physico-chemical properties of microplastics. In particular, in marine-exposed samples, a signature of biofilm development was detected. Speciation study indicates that iodine exists in the iodide form in the studied marine environment. The study revealed that, iodide ions attach to biofilm-developed microplastics via electrostatic, ion-dipole, pore filling, and van der Waals interactions. Pore filling, ion-dipole, and van der Waals interactions may cause iodide binding to irradiated microplastics, whereas pore-filling and van der Waals interactions cause iodide binding to pristine microplastics. The distribution coefficient (Kd) of iodine on microplastics is positively correlated with biofilm biomass, which signifies the role of biofilm in radioiodine uptake. The Kd indicates microplastics are potential iodide accumulators and could be a possible vector in the marine system.

RESUMEN

Soil to plant transfer factor (TF) of radionuclides is an important input parameter in dose assessment models. The wide range of TF for each radionuclide reported in the literature for a particular plant type indicates that radionuclide concentration in soil is not the only factor influencing its uptake by the plant. Different soil properties and agricultural practices may influence the TF and these are also a function of the climate. Considering the wide variation in TF data, here we attempt to review the available literature on TF of radionuclides in tropical countries of the Indian subcontinent (India, Bangladesh, and Sri Lanka). TF under equilibrium conditions are not available for all radionuclides, in such cases TF of naturally existing stable analogs elements were compiled. With an emphasis on, transfer of radionuclides from soil to the edible compartment of the plant; the TF data for 21 elements are compiled for 12 plant groups classified as per IAEA, Technical Reports Series No. 472. The article also presents the analysis and discussion of the extent and limitations of the compiled data. The compiled TF may be useful in assessing the food chain transfer of radionuclides when site-specific information is not available.

RESUMEN

In radioecological studies, soil to plant transfer factors (TF) is commonly used to estimate the food chain transfer of radionuclides, which is an important parameter to assess ingestion doses to humans. Rice is an important (Oryza sativa L.) staple crop in tropical countries and is the major food crop consumed all over the world. Out of the seven countries (India, Pakistan, Bangladesh, Nepal, Bhutan, and the island nations like Sri Lanka and Maldives) of the Indian subcontinent, Bangladesh, Sri Lanka, and Maldives along with a major region of India fall under tropical climate class according to Köppen climate classification. Because, the soil to rice TF under equilibrium conditions are not available for all radionuclides, TF of naturally existing stable elements, which are analogues of radionuclides were compiled. This review paper presents the collection of the TF data of soil to grain and stems & shoots of rice plant for eighteen elements. Data were generated mainly from different sub climatic regions of the tropical environment of India and Bangladesh. An overview of the compilation, analysis, and discussion of the extent and limitations of the data is presented.

RESUMEN

PURPOSE: To identify whether CGRP and PTHrP serve as screening biomarkers for early detection of preeclampsia or even before the development of preeclampsia in early pregnancy. METHODS: It was a nested case-control study. The subjects were divided into normotensive (controls) and preeclamptic (cases) groups. Serum samples of 132 cases and 132 controls were collected during pregnancy at three different gestational periods and one sample post delivery, from within the cohort of pregnant women reporting to antenatal clinic. Circulating levels of CGRP and PTHrP were analyzed by enzyme-linked immunosorbent assay. RESULTS: Maternal serum concentrations of CGRP and PTHrP increased with the advancement of gestation age in both normotensive and preeclamptic pregnancies but the significantly less increased levels were observed in preeclamptic pregnancies as compared with normotensive pregnancies. In postpartum period level of CGRP significantly falls in both groups although level of PTHrP continues to increase even after delivery. Maternal serum CGRP and PTHrP concentrations were positively correlated with the infant's birth weights. CONCLUSION: Maternal circulating CGRP and PTHrP concentrations were significantly lower in women with preeclampsia, which may contribute to the development of preeclampsia.
