Microbial Diversity In The Sawmill Environment: Implications On The Health Of Sawmill Workers And Merchants, Nigeria, Ebere J. Okafor-Elenwo Ej, Odaro S. Imade Os, Osazee E. Izevbuwa Eo

Journal of Bioresource Management

There is an increasingly high suspicion of occupational health diseases amongst workers in sawmill factories. Hence this study aimed to determine the microbial diversity in some sawmill factories in Okada, Edo State, Nigeria to evaluate potential implications of the factory’s processing area on the health of the workers and wood merchants. Bacteria and fungi count in the bioaerosols within the processing area of each factory was performed with the passive air sampling technique. While in the sawdust samples, microbial counts were carried out with the pour plate technique. Identification of the microbes was performed with macroscopic and microscopic examinations as …

Seroprevalence, Biochemical Investigation And Risk Factor Assessment For Hbv & Hcv Infection In Hospital Based Patients Of Islamabad, Pakistan, Narmeen Adnan Rana, Bushra Munir, Nazeer Hussain, Nazia Imtiaz, Muhammad Asif Gondal Dr., Fahed Parvaiz Dr.

Journal of Bioresource Management

Viral hepatitis poses a serious threat to mankind. Hepatitis B and C Virus are blood borne pathogens that affect millions of individually globally. This study was conducted on a hospital-based population in Islamabad, Pakistan over a period of 4 months, utilizing ELISA as the diagnostic technique which suggested a higher seroprevalence rate for both HBV and HCV i.e. 2.07% and 8.24% respectively. A correlational analysis of the biochemical parameters of these individuals with HBV and HCV infection was carried out and the results indicated a positive correlation of HBV with Alkaline Phosphatase (ALP), HCV with Total Bilirubin (TBil) and both …

Comment: Probably A Good News: Covid-19 Is Not Spreading Fast In Tropical Region Like In Temperate Region, Madeeha Manzoor

Journal of Bioresource Management

My understanding of Covid-19 is that, there are some climatic factors involved in seed spread of this virus. As it started from the area of China which falls under temperate zone, its second victim was Iran’s city Qom which also falls under temperate zone and third is Italy which is completely in temperate zone.

Data from two countries from Temperate zone and three countries from Tropical zone was compared. The days counted from the 100 cases each country reached as day one and further days studied on equal basis.

Functional Sites Within The Ihnv Nonvirion Protein That Regulate Host Cellular Responses, Jeff Ringiesn, Bartolomeo Gorgoglione, Douglas W. Leaman

Symposium of Student Research, Scholarship, and Creative Activities Materials

Fish Rhabdoviruses are responsible for causing fatal epizootics within commercial and wild populations of various fish species around the world. Infectious hematopoietic necrosis virus (IHNV), also known as the Salmonid novirhabdovirus, is enzootic along the Pacific Coast of North America and is comprised of five genogroups, each of which is endemic to a specific geographical location. Once the virus enters the host through the fin epithelia, IHNV infection causes infectious hematopoietic necrosis in salmonid species. The disease is highly fatal and presents with signs such as abdominal distension, bulging of the eyes, anemia, and necrosis of vital organs such as …

Anthrax Event Detection Using Twitter: Analysis Of Unigram And Bigrams For Relevant Vs Non-Relevant Tweets, Michele Miller, William L. Romine

Symposium of Student Research, Scholarship, and Creative Activities Materials

Due to the lack of anthrax attacks in recent times, researchers have used naturally occurring events to assess their anthrax detection models, but these provide little information on how the models will perform in the context of an unannounced, intentional release of a bioterrorism agent, like anthrax. Therefore, it is important to develop a detection model using data surrounding real anthrax scares and events.We develop a methodology to detect an anthrax-related event on Twitter. We describe a process to separate the tweets concerning anthrax-related events from those not related so experts can address misconceptions and fears in real-time.Most tweets were …

Enhanced Expression Of Receptor Tyrosine Kinase Mer (Mertk) On Socs3-Treated Polarized Raw 264.7 Anti-Inflammatory M2c Macrophages, Sankhadip Bhadra

Symposium of Student Research, Scholarship, and Creative Activities Materials

Macrophages are phagocytic cells located in tissues, organs and even circulated within our body as white blood cells. Based on the local cytokine milieu in tissue sites, macrophages may be polarized into pro-inflammatory M1 or anti-inflammatory M2 phenotypes. Receptor tyrosine kinase Mer (MERTK) helps in clearing dead neutrophils and other apoptotic cells from damaged tissue sites preventing chronic inflammation and autoimmune disorders. MERTK aids in the maintenance of tissue homeostasis and wound healing. Phosphatidylserine (PtdSer) present on the surface of apoptotic cells release “eat me” signals which are recognized by the two “bridging ligands” of MERTK receptor, Gas6 and ProS. …

Effect Of Homofermentative Inoculant On Fermentation Characteristics And Nutritive Values Of Corn Silage, Nafeesa Qudsia Hanif, Iffat Tahira, Nighat Sultana, Mujahid Hasan

Journal of Bioresource Management

An in vitro study was planned to assess the effects of a homofermentative microbial inoculant on the fermentation parameters and nutritive value of corn silage. The inoculant was applied at concentrations of 5x10⁴cfu/g of forage (T1), 1x10⁵cfu/g of forage (T2) 1.5x10⁵cfu/g of forage (T3) and a negative control group (T0) without bacterial inoculant in three replicates each. At day 3, 7, 45 and 90 of the experiment individual buckets were opened to characterize the material, quick acidification, dry matter recovery, and aerobic stability of silage respectively. The temperature of the trial samples was 32.75±1.92 …

The Persisting Threats Of Cholera: A Cyclical Public Health Problem In Ghana, Rita Laryea Amediavor

Browse all Theses and Dissertations

The prevalence of communicable diseases continues to be one of the continent's leading causes of deaths. Cholera is a waterborne disease triggered by toxigenic strains of the Gram-negative bacteria Vibrio Cholerae O1 strain and less common O139 strain. with symptoms such as severe acute watery diarrhea and vomiting leading to dehydration, progressing to hypovolemic shock and death if not treated timely due to its short incubation period (Pasetto et al., 2018). West African countries are largely portrayed as endemic to cholera, though the dynamics of outbreaks in these developing countries remain largely uncertain. The purpose of the study is to …

Potential Role Of Ahr In Antibody Production, Mili Bhakta

Aryl hydrocarbon receptor (AhR) mediates the immunosuppressive effects of 2,3,7,8 -tetrachlorodibenzodioxin (TCDD) in murine B cells. The effects of AhR activation on the regulation of expression of human immunoglobulin isotypes (μ, γ1-4, α1-2 and ε) and Ig secretion is unclear. Our previous results using CL-01 cell-line originating from a Burkitt’s lymphoma patient, demonstrated an inhibitory effect of TCDD on IgG expression but a surprising and marked loss of IgG secretion when the AhR was knocked out by siRNA or CRISPR/Cas9 gene editing. To determine if the AhR is a critical mediator of IgG expression, current study is focused on characterizing …
