Moderating effect of coworker support on the relationship between HRM practices, organizational climate, leadership styles and organizational commitment
This study was conducted among the academic staff in public higher education sector in Khyber Pakhtunkhwa (KPK), Pakistan. The main objective of the study was to determine the effect of human resource management practices, organizational climate, and leadership styles on organizational commitment. A total of 354 academic staff from universities located in the KPK, Pakistan participated in the study. The results revealed statistically significant support for the relationship between training and development and organizational commitment; compensation and organizational commitment; organizational climate and organizational commitment; transformational leadership style and organizational commitment; transactional leadership style and organizational commitment. However, no statistically significant support was found for the relationship between performance appraisal and organizational commitment. Moreover, the results reported moderating effect of coworker support over the relationship between compensation and organizational commitment; organizational climate and organizational commitment; transformational leadership style and organizational commitment; and transactional leadership style and organizational commitment. On the contrary, the results could not find support for the moderating effect of coworker support on the relationship between training and development and organizational commitment; and between performance appraisal and organizational commitment. In general, the empirical relationships between HRM practices, organizational climate, leadership style, coworker support, and organizational commitment suggested that it would be beneficial to the management of public sector universities to enhance organizational commitment. Besides that, theoretical and practical implications are also discussed
Can interleukin-6 promote human colorectal cancer progression through changes in microRNA expression?
Colorectal cancer (CRC) is the third most common cancer worldwide with over a million new cases each year. Eighty percent of CRC cases have no genetic predisposition and result from a series of epigenetic and genetic alterations, referred to as ‘sporadic’ CRC. Diets rich in red or processed meats (containing dietary carcinogens) as well as bowel inflammation are a major risk factors for disease, however the underlying mechanisms are not yet well understood. Upregulation of pro-inflammatory cytokines and cytochrome P450 (CYP450) enzymes that activate dietary carcinogens as well as microRNA (miRNA) dysregulation have been observed in CRC tissue. Interleukin-6 (IL6) is a multifunctional cytokine thought to play numerous roles in tumour progression including activation of tumour-promoting signalling pathways, epigenetic gene regulation and alteration of DNA repair mechanisms; thus presence of IL6 may be key to promoting CRC tumour progression. I hypothesised that elevated levels of IL6 in the tumour microenvironment (TME) could alter miRNA expression and induce local activation of dietary carcinogens, thereby stimulating epigenetic and genetic changes that promote CRC. The current project investigated this hypothesis using a mechanistic approach with in vitro cell culture techniques. Phenotypic changes in response to IL6 treatment were observed and the underlying causes were determined by performing genetic and epigenetic studies. The findings from this project identified three potential mechanisms of IL6-mediated CRC promotion, which involve miRNAs, STAT3 signalling and DNA methylation. First, IL6 promoted dietary carcinogen-mediated DNA damage by inducing CYP450 expression. Second, IL6 stimulated CRC cell proliferation, migration and invasion through gene and miRNA expression changes. Third, IL6-
mediated CRC-immune cell crosstalk in the TME resulting in the maintenance of IL6 secretion. Taken together, these data suggest that IL6 plays multiple roles in promoting CRC. Understanding these molecular events could lead to better prevention and therapeutic strategies.Open Acces
Impact of Training and Development and Supervision Support on Organizational Effectiveness
The current study explores the effect of training and development and supervisor support on organizational effectiveness. The main focus of the study is to clarify that how effectively telecom sector of Pakistan can achieve it intended outcomes, through training and development and supervisor support. A survey structure was used to gather data from 2017 employees working at the Telecom Center. Both descriptive and inferential statistical methods were the basis for the results. A positive relationship between training and development and organisational support is determined by the results of the study, although similar positive relationships have also been identified between supervisory support and organisational support
DALK (MASSAGE) AND ITS IMPLICATION IN THERAPY ACCORDING TO UNANI SYSTEM OF MEDICINE: A REVIEW
According to classical literature of Unani Medicine, management of any disease depends upon the diagnosis of disease. In the diagnosis, clinical features, i.e., signs, symptoms, laboratory investigations and Mizaj (temperament) are important. Any cause or factor is countered by Quwwat Mudabbira lil-Badan (medicatrix naturae: the power of body responsible to maintain health), the failing of which may lead to quantitatively or qualitatively derangement of the normal equilibrium of Akhlat (humors) of body which constitute the tissues and organs. After diagnosing the disease, Usul-e-Ilaj (principle of treatment) of disease is determined on the basis of etiology. The principle of management is decided which may be one or more of the four types of treatment lines such as Ilaj bil-Tadbeer (Regimental therapy), Ilaj bil-Ghiza (Diet therapy), Ilaj bil-Dawa (Pharmacotherapy), Ilaj bil-Yad or Jarahat (Surgery). Ilaj bil-Tadbeer is most preferred one. Dalk is one of the most important parts of Ilaj bil-Tadbeer. Details about Dalk have been mentioned in Unani Literature, some of them are described in this paper
Interaction Between Hydrogen Sulphide (H2s) And Nitric Oxide (No) In Left Ventricular Hypertrophy And Their Effect On Responsiveness Of Alpha I-adrenergic Receptors Subtypes In The Rat Kidney
The present study investigated the effect of left ventricular hypertrophy
(LVH) on the responsiveness of (II-adrenergic receptor subtypes to adrenergic
stimuli in the rat. The role of hydrogen sulphide (H2S) and nitric oxide (NO) systems
and their interaction in the progression of LVH was studied by examining the effect
of altered expression of cystathione y lyase (CSE mRNA) and endothelial nitric
oxide synthase (eNOS mRN A) in the heart during LVH. Cardiovascular parameters
such as cardiac geometry, oxidative stress, arterial stiffness and vascular
responsiveness to vasoactive stimuli were studied. In addition, this study examined
renal excretory functions, haemodynamics and histopathological changes after
exogenous administration of NaHS, an H2S donor, L-arginine, an NO donor and a
combination of NaHS and L-arginine. Wistar-Kyoto (WKY) rats were divided into
two major groups of Control and LVH. These groups were then subdivided into 8
groups based on treatment. NaHS (56JlM/kg I.P. for 5 weeks) or L-arginine (1.25g1L
for 5 weeks in drinking water) treated control or LVH groups. LVH was induced
using isoprenaline (Smg/kg, S.c. every 72 hours for 2 weeks) and caffeine (62mglL
in drinking water for 2 weeks). The uj-adrenergic receptors subtypes was studied by
examining the responsiveness to noradrenaline (NA), phenylephrine (PE) and
methoxamine (ME) in the presence of a background intrarenal infusion of selective
uj-adrenergic receptors blockers (5-methylurapidil (5-MeU), chloroethy1clonidine
(CEC) and BMY 7378). Real-time quantitative peR data (normalized t
