Gene Sequence of Rubella Virus Infection in Serum of Wives That Correlate to Intrauterine Insemination Success Rate in Baghdad's Population Couples
The current study focused on the prevalence of Rubella virus disease among wives who underwent the process of artificial insemination (IUI) and its relationship to the elevated proportion of free radicals in the blood plasma and its correlation with water pollution in the spreading of the disease for the period from 15/2/2022 to 1/2/2023 in private laboratory for IUI procedure (AL- Amal). The study included 60 women who underwent (IUI) procedure and have positive results for Rubella virus (IgG and IgM) compared to wives who tested negative for Rubella virus for ages groups from 20 to 35 years
The Scenario of Zakah Management in Bangladesh: A Critical Analysis
The aim of the study is to describe and analyze the real scenario of zakah management in Bangladesh. Zakah is an important tool to eradicate poverty in the country and it can play a vital role in alleviating unemployment too. About 91.04% of the total population of the country is Muslim. A good number of Muslims are capable of paying zakah annually. However, the zakah management system in urban or rural areas is poor. And the capable people on whom zakah is compulsory are not so positive about distributing zakah among (mustahaqqun) the beneficiary group. Mustahaqqun means the class of people who are eligible to collect zakah according to Islamic Shariah. Almost, all the zakah payers are not aware enough to pay zakah in the defined Sariah way. Only a few people legally pay their zakah portion among the eligible class. For this, the actual method of zakah distribution management in Bangladesh is not exercised and executed properly. This is why, the real beneficiary group is not facilitated in a systematic way. This study also tries to focus on the challenges of zakah distribution management in Bangladesh and tries to highlight the effective recommendations for resolving these problems
Prevalence of Helicobacter Pylori Infection and Infertility Problems Among Baghdad City Populations: Associations with Food Habits and Environmental Pollution
This study aimed to determine the incidence of Helicobacter pylori infection among Baghdad city populations and explore associations with infertility, food habits, environmental factors, and comorbidities like type 2 diabetes mellitus (T2DM). The researcher examined 120 people in Baghdad from June 2020 to March 2022. H. pylori antibodies were detected using rapid diagnostic kits. Information on age, gender, food habits, T2DM, smoking status, and living conditions was collected. Semen analysis was done in H. pylori positive and negative males with infertility. H. pylori seroprevalence was 62.5%. Prevalence increased with age (p<0.05) and was higher among females (70%) than males (62.5%), (p<0.001). Non-spicy food consumers showed higher prevalence (67%) than spicy food eaters (33%), (p<0.001). T2DM patients demonstrated substantially higher prevalence than non-diabetics (81% vs 67%), (p=0.001). Rural inhabitants revealed greater prevalence than urban dwellers (66.6% vs 33.3% for males; 70% vs 40% for females), (p<0.01). Smokers exhibited higher seropositivity than non-smokers (41% vs 24%), (p<0.001). Infertile men showed poorer semen parameters with H. pylori infection (p<0.01). Good hygiene, healthy diets, and avoiding smoking are vital to curb H. pylori infection. Testing for this bacterium should be considered in infertility assessments
Development of Emergency Planning and Response Model Based on OSHA Process Safety Management Requirement
When incidents happen and the consequences are not mitigated effectively,
one of the indicated failures consists of ineffective emergency response planning
(EPR). EPR is an important aspect of the Process Safety Management (PSM)
Standards and the guidelines are stated in CFR 1910.119 (n) which explains the
minimum elements of emergency response and procedures in handling emergency or
small releases. Despite its implementation in 1992, CSB finds ineffective EPR system
in certain accidents such as the Missouri DPS Enterprise Chlorine Gas Release
accident in 2002. DPS EPR failed in planning on location of emergency equipment
and accessibility. Many other accidents has occurred throughout the decade and even
though organizations have their own EPR system, there are issues in meeting
minimum PSM requirements. There also exists the problem of self-regulatory policies
practiced by organizations which might not meet these requirements as well. To help
organizations meet these minimum requirements, the purpose of this paper is to
present a structured and easy technique to plan and implement EPR as per PSM
requirements. A model has been developed based on this technique and its application
has been tested as a case study in a refinery in Malaysia and discussed in this report.
The results reflected the feasibility of this model as it helped users track and manage
documents better. This technique has the potential to help users manage EPR better to
reduce adverse impacts to people, environment and asset
Longitudinal growth of mammalian bones: a possible role for membrane transporters in mediating chondrocyte hypertrophy
Long bone lengthening occurs at the growth plate (GP) by well-regulated
chondrocyte proliferation, hypertrophy and terminal matrix deposition. GP
chondrocyte (GPC) hypertrophy has been implicated to be the main determinant of
bone growth rate; however the mechanism is poorly understood. The work of this
thesis examined some of the cellular process that drives the chondrocyte swelling
or hypertrophy particularly in a mammalian post natal GPs using living in situ GPC
and fixed GP tissues.
Confocal scanning microscopy (CLSM) was used to determine living in situ
GPC volume and dimension changes in proliferative zone (PZ) through to
hypertrophic zone (HZ) chondrocytes of different GPs of various bones. While PZ
cells showed similar volumes and dimensions, HZ cells varied in different GPs,
even within the same long bone but at opposite ends. However, the hypertrophic
cell volume measured at a single post natal age (day 7) was independent of the
corresponding bone length. This could reflect a complex interplay between local
and systemic factors in different GPs, which occurs throughout the active phase of
bone growth.
Maintaining GPC morphology was critical in studying GPC hypertrophy
using fixed tissues. This work highlighted a problem caused by conventional
fixative solutions, which caused up to 44% hypertrophic GPC shrinkage following
GP fixation. This artifact appeared to be associated with the hyperosmotic nature of
the fixatives used and could be abolished by adjusting the fixative osmolarity close
to physiological level (280 mOsm), or could be significantly reduced by bisecting
bone tissues prior to tissue fixation.
This thesis proposed roles for plasma membrane transporter(s) in mediating
GPC hypertrophy. This hypothesis was tested by examining roles of sodium-hydrogen exchanger (NHE) and anion exchanger (AE) in GPC hypertrophy using
an ex vivo bone growth inhibition model. Inhibition of bone growth by inhibitors of
NHE (EIPA) and AE (DIDS) respectively was shown to be dose-dependent. The
histology of bones demonstrated that the late HZ width was significantly reduced
in GPs treated with EIPA or DIDS. Although in situ GPC volumes in the PZ and
HZ were not notably different in DIDS-treated GP, the cell volumes in both zones
were significantly reduced by EIPA treatment. Fluorescence
immunohistochemistry revealed distinctive cellular localisations of NHE1 and AE2
in the PZ and early HZ. These results suggest a possible role of AE in mediating
GPC volume increase in PZ chondrocytes and those in the early stages of cell
hypertrophy, whereas NHE could possibly maintain intracellular pH of GPC
throughout all GP zones.
This thesis has characterized various changes in volume and dimensions of
living in situ GPC from PZ through to HZ of different GPs of postnatal rats. This
work emphasized the importance of fixative osmolarity in order to accurately
preserve the normal volume/morphology of cells within tissues. Most importantly,
this thesis confirmed a potential role of the plasma membrane transporters, AE and
NHE in GPC hypertrophy of growing bones
