Prevalence of Psychological Distress among Undergraduate Medical Students: A Cross-Sectional Study.

Background: Stressful environment in medical school often has a negative effect on students' psychosocial well-being. An in-depth understanding of how medical students experience psychological distress and coping is necessary for the prospective students.

Objectives: To estimate the prevalence of psychological distress among undergraduate medical students and its association with some demographic factors.

A 678-W Frequency-Modulation-Based ADC With 104-dB Dynamic Range in 44-kHz Bandwidth.

This brief presents a frequency-modulation-based analog-to-digital converter (FM ADC) that takes advantage of the coding gain resulting from bandwidth expansion in the analog domain of FM systems to achieve high dynamic range and incorporates a highly digital demodulation approach for power efficiency. The novel architecture employs a sinusoidal output voltage-controlled oscillator (VCO), a relatively low-resolution successive approximation register ADC to sample signals in the FM domain, and then a digital signal processing FM demodulator to recover high-resolution samples of the VCO's original analog input. The proposed ADC is implemented in 0.

Evaluation of N-terminal pro-B-type natriuretic peptide and high-sensitivity C-reactive protein relationship with features of metabolic syndrome in high-risk subgroups for cardiovascular disease.

Aim: This study evaluating N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) and high-sensitivity C-reactive protein (hs-CRP) relationship with features of the metabolic syndrome (MS) in high risk subgroups for cardiovascular disease (CVD) in Trinidad.

Materials And Methods: The sample population consisted of 160 subjects, 78 of whom were African and 82 East Indian attending medical outpatient clinics of regional health authority hospitals of Trinidad.

Results: Systolic blood pressure, triglycerides, glucose and insulin as well as NT-pro-BNP were elevated among the East Indian sub-population, with only systolic blood pressure being significantly elevated among the African sub-population.

Neurolaena lobata L. promotes wound healing in Sprague Dawley rats.

Background: The leaves of the Neurolaena lobata (Asteraceae) plant are used to control diabetes and heal wounds and infections.

Aim: The ethanolic extract of N. lobata leaf was evaluated for its ability to heal inflicted wounds in rats using the excision wound model.

Wound-healing potential of an ethanol extract of Carica papaya (Caricaceae) seeds.

Carica papaya L. (Linn) (Caricaceae) is traditionally used to treat various skin disorders, including wounds. It is widely used in developing countries as an effective and readily available treatment for various wounds, particularly burns.

Antarth, a polyherbal preparation protects against the doxorubicin-induced toxicity without compromising its Antineoplastic activity.

Doxorubicin (DOX), an anthracycline drug widely used for the treatment of various cancers, causes a cumulative dose-dependent cardiotoxicity that is characterized by an irreversible dilated cardiomyopathy and congestive heart failure. Antarth (ANT) a polyherbal preparation was evaluated for its cardioprotective properties against doxorubicin-induced cardiotoxicity in mice. Mice were treated with 25 mg/kg ANT orally once daily for 5 consecutive days before a single intraperitoneal injection of 15 mg/kg doxorubicin.
