    Human resources is one of important assets functions as a mover of company\u27s operation to obtain high efficiency as well as high productivity. The objective of this research is to find out the application of Occupational Health and Safety (OHS) in PT Ferron Par Pharmaceutical (Ferron), Bekasi. Ferron is a very fast growing company dealing with pharmaceutical industry, which applies OHS in its production process .Method of data collection performed with the ways of : observing directly the activities applying OHS; interviewing or asking staffs questions; and reviewing literature. While descriptive analysis is used by matching the result of the research and theories in the literature. The analysis concludes that functions and benefits of applying OHS cover all aspects and steps in the theories completely. Keywords: Application, descriptive analysis, occupational health and safety (OHS), pharmaceutical industry

    Factors Influencing Farm Crime in Kenya: Opinions and Experiences of Farmers

    Although agriculture is the backbone of Kenya’s economy, the industry is faced with rapid social, cultural, economic, and technological changes that have significantly increased crime levels in rural areas. In particular, communal, social, and individual controls are diminishing, and the result is an increase of criminal activities against agricultural operations. The aim of the study was to assess factors associated with levels of agricultural theft and vandalism in Kenya, based on the perceptions of farmers themselves. The research was carried out in the Soy division of Uasin Gishu County. A multistage sampling approach, which incorporates purposive, random, and systematic techniques, was used to select respondents within the case study locations. A semi-structured questionnaire was administered to a representative sample of 200 farmers. Key informant interviews and informal discussions were conducted with local administration officers, namely, village elders, sub chiefs and chiefs, to supplement information derived from the survey. The study used routine activity theory to explain how perceived changes in communities where the farmers lived have created opportunities for the commission of crime. Based on the findings, the study recommends programs which create employment opportunities for both youth and disadvantaged persons in rural Kenya

    Topical fluorouracil after surgery for ocular surface squamous neoplasia in Kenya: a randomised, double-blind, placebo-controlled trial

    BACKGROUND: Ocular surface squamous neoplasia (OSSN) is an aggressive eye tumour particularly affecting people with HIV in Africa. Primary treatment is surgical excision; however, tumour recurrence is common. We assessed the effect of fluorouracil 1% eye drops after surgery on recurrence. METHODS: We did this multicentre, randomised, placebo-controlled trial in four centres in Kenya. We enrolled patients with histologically proven OSSN aged at least 18 years. After standard surgical excision, participants were randomly allocated to receive either topical fluorouracil 1% or placebo four times a day for 4 weeks. Randomisation was stratified by surgeon, and participants and trial personnel were masked to assignment. Patients were followed up at 1 month, 3 months, 6 months, and 12 months. The primary outcome was clinical recurrence (supported by histological assessment where available) by 1 year, and analysed by intention to treat. The sample size was recalculated because events were more common than anticipated, and trial enrolment was stopped early. The trial was registered with Pan-African Clinical Trials Registry (PACTR201207000396219). FINDINGS: Between August, 2012, and July, 2014, we assigned 49 participants to fluorouracil and 49 to placebo. Four participants were lost to follow-up. Recurrences occurred in five (11%) of 47 patients in the fluorouracil group and 17 (36%) of 47 in the placebo group (odds ratio 0·21, 95% CI 0·07–0·63; p=0·01). Adjusting for passive smoking and antiretroviral therapy had little effect (odds ratio 0·23; 95% CI 0·07–0·75; p=0·02). Adverse effects occurred more commonly in the fluorouracil group, although they were transient and mild. Ocular discomfort occurred in 43 of 49 patients in the fluorouracil group versus 36 of 49 in the placebo group, epiphora occurred in 24 versus five, and eyelid skin inflammation occurred in seven versus none. INTERPRETATION: Topical fluorouracil after surgery substantially reduced recurrence of OSSN, was well-tolerated, and its use recommended

    Expansion of Inefficient HIV-Specific CD8 T Cells during Acute Infection

    ABSTRACT Attrition within the CD4 + T cell compartment, high viremia, and a cytokine storm characterize the early days after HIV infection. When the first emerging HIV-specific CD8 + T cell responses gain control over viral replication it is incomplete, and clearance of HIV infection is not achieved even in the rare cases of individuals who spontaneously control viral replication to nearly immeasurably low levels. Thus, despite their partial ability to control viremia, HIV-specific CD8 + T cell responses are insufficient to clear HIV infection. Studying individuals in the first few days of acute HIV infection, we detected the emergence of a unique population of CD38 + CD27 − CD8 + T cells characterized by the low expression of the CD8 receptor (CD8 dim ). Interestingly, while high frequencies of HIV-specific CD8 + T cell responses occur within the CD38 + CD27 − CD8 dim T cell population, the minority populations of CD8 bright T cells are significantly more effective in inhibiting HIV replication. Furthermore, the frequency of CD8 dim T cells directly correlates with viral load and clinical predictors of more rapid disease progression. We found that a canonical burst of proliferative cytokines coincides with the emergence of CD8 dim T cells, and the size of this population inversely correlates with the acute loss of CD4 + T cells. These data indicate, for the first time, that early CD4 + T cell loss coincides with the expansion of a functionally impaired HIV-specific CD8 dim T cell population less efficient in controlling HIV viremia. IMPORTANCE A distinct population of activated CD8 + T cells appears during acute HIV infection with diminished capacity to inhibit HIV replication and is predictive of viral set point, offering the first immunologic evidence of CD8 + T cell dysfunction during acute infection

    Blood Feeding and Insulin-like Peptide 3 Stimulate Proliferation of Hemocytes in the Mosquito Aedes aegypti

    All vector mosquito species must feed on the blood of a vertebrate host to produce eggs. Multiple cycles of blood feeding also promote frequent contacts with hosts, which enhance the risk of exposure to infectious agents and disease transmission. Blood feeding triggers the release of insulin-like peptides (ILPs) from the brain of the mosquito Aedes aegypti, which regulate blood meal digestion and egg formation. In turn, hemocytes serve as the most important constitutive defense in mosquitoes against pathogens that enter the hemocoel. Prior studies indicated that blood feeding stimulates hemocytes to increase in abundance, but how this increase in abundance is regulated is unknown. Here, we determined that phagocytic granulocytes and oenocytoids express the A. aegypti insulin receptor (AaMIR). We then showed that: 1) decapitation of mosquitoes after blood feeding inhibited hemocyte proliferation, 2) a single dose of insulin-like peptide 3 (ILP3) sufficient to stimulate egg production rescued proliferation, and 3) knockdown of the AaMIR inhibited ILP3 rescue activity. Infection studies indicated that increased hemocyte abundance enhanced clearance of the bacterium Escherichia coli at lower levels of infection. Surprisingly, however, non-blood fed females better survived intermediate and high levels of E. coli infection than blood fed females. Taken together, our results reveal a previously unrecognized role for the insulin signaling pathway in regulating hemocyte proliferation. Our results also indicate that blood feeding enhances resistance to E. coli at lower levels of infection but reduces tolerance at higher levels of infection
