Modeling Ion Channel Flux in Transmembrane Proteins

The transmembrane proteins known as ion channels play a role in controlling and preserving the ionic concentrations across the cell membrane. Modeling the flux of ions in and out of these channels on an atomic level is essential for understanding several neurological diseases and related pharmaceutical discoveries. Recent experimental research has provided information on the channel's physical structure which can be used to create realistic ion transport models. Different trajectories exist f...

Worm Sorting using Sine Wave Microfluidic Channels

This paper looks at a movement-based assay to analyze adaptability in Caenorhabditis elegans locomotion behavior. A series of sinusoidal microchannels of fixed wavelength and varying amplitude, with the width being similar to the body diameter of the organism, are used for this purpose. The worms are allowed to enter the channel from the input and transition towards the output port. In sections that are similar to the worms' undulations, the movement is fast and steady. However, as the channe...

The Mycological Deterioration of Maize Stored in Different Facilities Within Enugu Metropolis

Abstract This research was carried out to study the mycological deterioration of stored maize in different storage facilities within Enugu metropolis. The study was carried out in some selected markets and homes in Enugu State, Nigeria this involved a cross-sectional study which covered four (4) different market locations (Akwata, Gariki, New market, Abakpa market and two (2) different homes (Thinkers corner and Ugwuaji) with different storage methods (storage in gallons and in kitchen chimne...

Fruit and Vegetable Contamination with Medically Important Geohelminths and Gastrointestinal Protozoa in Oyi Local Government Area, Anambra State, Nigeria

Abstract This study was conducted to determine the level of fruits and vegetable contamination with medically important geohelminths and gastrointestinal protozoan parasites in Oyi Local Government Area. A total of 600 fruits and vegetables were purchased from the daily markets located in five communities in the study area in the morning hours from 7:00 am to 10:00 am. They were washed with saline water and examined microscopically for helminths and gastrointestinal protozoan parasites by sed...

Accessibility and Use of Family Planning Information (FPI) by Rural People in Kilombero District, Tanzania

Abstract This study investigated the accessibility and use of family planning information (FPI) by rural people in Kilombero District, Tanzania. The purpose was to examine the entire infrastructure required for accessing and using FPI in a rural setting. The study surveyed 120 respondents using questionnaire, interview protocols and observation guides. The respondents included women and men of reproductive age, and Maternal and Child Health (MCH) clinic staff. The study revealed that there i...

Community Poultry Project for Conserving the Wildlife Species in Magombera Forest, Tanzania

ABSTRACT Aims: Poaching of wildlife is a major challenge in their conservation, including endemic ones like Procolobus gordonorum Matschie. Local communities in Udzungwa and Magombera poach for subsistence and small scale commerce. The Community poultry project adjacent to Magombera forest contributed towards enhancing the conservation of wildlife species through providing community with poultry as an alternative livelihood where meat and income can be generated in legal and convenient metho...

Heavy Metals Bio-Accumulation In Tilapia And Catfish Species In Lake Rukwa Ecosystem Tanzania

ABSTRACT Investigation on accumulation of selected heavy metals of Zinc, Mercury, Copper, Lead, Chromium and Nickel in sediment, water and muscle tissues of Clarias gariepinus (African catfish) and Oreochromis esculentus (Singida tilapia) fish was done in Lake Rukwa, Tanzania. Samples were obtained from transects of 100 m long extending from Luika and Songwe River mouths to offshore. Water and sediment samples were collected directly from the study sites while fish were obtained from fisherf...

Antimicrobial Activity of Lemon Grass (Cymbopogon Citratus) on Clinical Isolates of Pseudomonas Aeruginosa, Salmonella Typhi, Streptococcus Pyogenes and Candida Albicans

ABSTRACT Cymbopogon citratus, commonly known as lemongrass due to its lemon fragrance when crushed. Due to the presence of many phytochemicals in lemongrass, their use in the treatment of illnesses has increased. The antimicrobial activity of Cymbopogoncitratus (Lemongrass) was evaluated on Pseudomonas aeruginosa, Salmonella typhi, Streptococcus pyogenes and Candida albicans. The extract was obtained using two solvents; ethanol and methanol. The antimicrobial activity of the extracts was test...
