Pain/Stress, Mitochondrial Dysfunction, and Neurodevelopment in Preterm Infants.

Introduction: Preterm infants experience tremendous early life pain/stress during their neonatal intensive care unit (NICU) hospitalization, which impacts their neurodevelopmental outcomes. Mitochondrial function/dysfunction may interface between perinatal stress events and neurodevelopment. Nevertheless, the specific proteins or pathways linking mitochondrial functions to pain-induced neurodevelopmental outcomes in infants remain unidentified.

Parental metal exposures as potential risk factors for spina bifida in Bangladesh.

Background: Neural tube defects are a pressing public health concern despite advances in prevention from folic acid-based strategies. Numerous chemicals, in particular arsenic, have been associated with neural tube defects in animal models and could influence risk in humans.

Objectives: We investigated the relationship between parental exposure to arsenic and 17 metals and risk of neural tube defects (myelomeningocele and meningocele) in a case control study in Bangladesh.

Topical Pilocarpine Formulation for Diagnosis of Cystic Fibrosis.

Cystic fibrosis is diagnosed in infants by estimating the levels of chloride ions present in the sweat induced by iontophoresis of pilocarpine solution. Elevated levels of chloride (≥60 mMol/L) in sweat are indicative of cystic fibrosis. However, the iontophoretic method of delivering pilocarpine is cumbersome and usually is associated with several side effects such as skin burn, skin rashes, erythema, and so forth.

Assessment of physicians' knowledge to combat obesity in Bangladesh.

Objective: Physicians need to play a proactive role to combat obesity and its associated comorbidities. The present survey was conducted to assess the awareness, knowledge, practice and attitude of the physicians in Bangladesh in the prevention and management of obesity.

Methods: Three hundred physicians were randomly selected from a medical university, a government medical college and a private medical college in Bangladesh to be included in this survey.

Vitamin D and Parathyroid Hormone Status in Female Garment Workers: A Case-Control Study in Bangladesh.

Despite the abundant sunlight, vitamin D deficiency is prevalent in South Asian countries including Bangladesh. Information on vitamin D level is insufficient in adults particularly in female garment workers in Bangladesh. This study was designed to evaluate the status of vitamin D, parathormone (PTH), calcium, and alkaline phosphatase (ALP) among the female garment workers in Bangladesh.

Biomarkers of cardiovascular and metabolic diseases in otherwise healthy overweight subjects in Bangladesh.

Biomarkers of cardiovascular and metabolic diseases were assessed in Bangladeshi overweight subjects categorized by Asian BMI criteria. After screening 300 people, 90 apparently healthy subjects were enrolled and grouped into normal weight, overweight and obese. Compared to normal weight, the overweight and obese groups showed significant elevation of serum triglyceride, insulin, homocysteine, insulin resistance/sensitivity, and atherogenic index of plasma.

Does the Interdependence between Oxidative Stress and Inflammation Explain the Antioxidant Paradox?

Oxidative stress has been implicated in many chronic diseases. However, antioxidant trials are so far largely unsuccessful as a preventive or curative measure. Chronic low-grade inflammatory process, on the other hand, plays a central role in the pathogenesis of a number of chronic diseases.

Relationship of Soluble RAGE with Insulin Resistance and Beta Cell Function during Development of Type 2 Diabetes Mellitus.

This study examined whether circulating levels of soluble receptor for advanced glycation end products (sRAGE) alter in prediabetes and correlate with insulin resistance (IR) and beta cell function in prediabetes and newly diagnosed type 2 diabetes mellitus (T2DM). Subjects without previous history of diabetes were recruited and grouped as control, prediabetes, and newly diagnosed T2DM. The control subjects (n = 40) and people with prediabetes (n = 52) and diabetes (n = 66) were similar in terms of age, sex, BMI, systolic and diastolic BP, and fasting insulin level.

Performance of kala-azar surveillance in Gaffargaon subdistrict of Mymensingh, Bangladesh.

Introduction: Elimination of kala-azar is planned for South Asia requiring good surveillance along with other strategies. We assessed surveillance in Gaffargaon upazila (a subdistrict of 13 unions) of Mymensingh district, Bangladesh highly endemic for kala-azar.

Methods: In 4703 randomly sampled households, within nine randomly sampled villages, drawn from three randomly sampled unions, we actively searched for kala-azar cases that had occurred between January 2010 and December 2011.

Antinociceptive and antioxidant potential of the crude ethanol extract of the leaves of Ageratum conyzoides grown in Bangladesh.

Context: Ageratum conyzoides Linn. (Asteraceae) is an annual herbaceous plant with a long history of traditional medicinal and agricultural uses; it is usually grown in the northeast part of Bangladesh.

Objective: The ethanol extract of the plant leaves was evaluated for preliminary phytochemical screening with its antinociceptive and antioxidant activities.

Phytochemical investigation and in vitro antinociceptive activity of Clerodendrum indicum leaves.

The crude ethanolic extracts of Clerodendrum indicum Linn. leaves were investigated for possible antinociceptive activity using acetic acid induced writhing model in mice. Phytochemical analysis was also carried out according to the standard procedures to identify the presence of different phytoconstituents in the ethanolic extract of the plant leaves.

Phytochemical screening, cytotoxicity and antibacterial activities of two Bangladeshi medicinal plants.

The objectives of the present study were to investigate phytochemical screening and to assay cytotoxicity and antibacterial activities of ethanolic extracts of leaves of two medicinal plants, Aglaonema hookerianum Schott (Family: Araceae) and Lannea grandis Engl. (Family: Anacardiaceae) available in Bangladesh. The brine shrimp lethality bioassay showed that the ethanolic extracts of Aglaonema hookerianum and Lannea grandis possessed cytotoxic activities with LC50 5.
