EMPLOYER BRANDING: A STUDY OF PSU'S

Employer branding involves efforts on the part of employer to promote self on the grounds of its uniqueness and desirability as an employer, both within and outside the firm. Employer branding has gained immense popularity amongst practicing managers in recent years. Therefore, the quest was to study the relationship of Employer Branding with the two very strategically important constructs, i.e., Motivation and Intention to Stay. Development of questionnaire was carried out with the help of standardized scale and was utilized to measure the perception of employees from four public sector undertakings (PSU), namely, State Bank of India (SBI), Punjab National Bank (PNB), Indian Oil Corporation Limited (IOCL), and Oil and Natural Gas Commission (ONGC). The sample size was of 120 respondents which included the employees from top level, middle level, and junior level management. The statistical tests employed for this research investigation were Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and Structural Equation Modelling (SEM). It was found that Employee Motivation explains Employer Branding to the tune of 85%, whereas Employer Branding is further explaining “Intention to Stay” to the extent of 25%. Being based on the primary data, the accuracy of the study is dependent on the reliability of the responses given by the respondents. The outcomes of the study would be useful for the PSU’s to strategize their priorities in order to create a good Employer Brand by motivating employees and thereby retaining employees. The linkage between motivation of employees, Intention to Stay, and Employer Branding has been explored in this study, and this could be probably showcasing the importance of motivating the employees to usher in a good image for the organization. The researchers have also developed a unique model which could be followed by the organizations to curb attrition

Macrocyclic colibactin induces DNA double-strand breaks via copper-mediated oxidative cleavage.

Colibactin is an assumed human gut bacterial genotoxin, whose biosynthesis is linked to the clb genomic island that has a widespread distribution in pathogenic and commensal human enterobacteria. Colibactin-producing gut microbes promote colon tumour formation and enhance the progression of colorectal cancer via cellular senescence and death induced by DNA double-strand breaks (DSBs); however, the chemical basis that contributes to the pathogenesis at the molecular level has not been fully characterized. Here, we report the discovery of colibactin-645, a macrocyclic colibactin metabolite that recapitulates the previously assumed genotoxicity and cytotoxicity. Colibactin-645 shows strong DNA DSB activity in vitro and in human cell cultures via a unique copper-mediated oxidative mechanism. We also delineate a complete biosynthetic model for colibactin-645, which highlights a unique fate of the aminomalonate-building monomer in forming the C-terminal 5-hydroxy-4-oxazolecarboxylic acid moiety through the activities of both the polyketide synthase ClbO and the amidase ClbL. This work thus provides a molecular basis for colibactin's DNA DSB activity and facilitates further mechanistic study of colibactin-related colorectal cancer incidence and prevention

Relapsing insulin-induced lipoatrophy, cured by prolonged low-dose oral prednisone: a case report

<p>Abstract</p> <p>Introduction</p> <p>Circumscript, progressing lipoatrophy at the insulin injection sites is an unexplained, however rare condition in diabetes mellitus.</p> <p>Case presentation</p> <p>We report a case of severe localised lipoatrophy developing during insulin pump-treatment (continuous subcutaneous insulin infusion) with the insulin analogue lispro (Humalog^®) in a woman with type-1 diabetes mellitus. After 11 months of progressing lipoatrophy at two spots on the abdomen, low-dose prednisone (5-10 mg) p.o. was given at breakfast for 8 months, whereby the atrophic lesions centripetally re-filled with subcutaneous fat tissue (confirmed by MRI) despite ongoing use of insulin lispro. However, 4 weeks after cessation of prednisone, lipoatrophy relapsed, but resolved after another 2 months of low-dose prednisone. No further relapse was noted during 12 months of follow-up on insulin-pump therapy with Humalog^®.</p> <p>Conclusion</p> <p>Consistent with an assumed inflammatory nature of the condition, low-dose oral prednisone appeared to have cured the lipoatrophic reaction in our patient. Our observation suggests a temporary intolerance of the subcutaneous fat tissue to insulin lispro (Humalog^®), triggered by an unknown endogenous mechanism.</p

Vasospasm in children with traumatic brain injury

To determine the incidence of vasospasm in children who have suffered moderate to severe traumatic brain injury. A prospective observational pilot study in a 24-bed pediatric intensive care unit was performed. Twenty-two children aged 7 months to 14 years with moderate to severe traumatic brain injury as indicated by Glasgow Coma Score ≤12 and abnormal head imaging were enrolled. Transcranial Doppler ultrasound was performed to identify and follow vasospasm. Patients with a flow velocity in the middle cerebral artery (MCA) &gt;120 cm/s were considered to have vasospasm by criterion A. If flow velocity in the MCA was &gt;120 cm/s and the Lindegaard ratio was &gt;3, vasospasm was considered to be present by criterion B. Patients with basilar artery (BA) flow velocity &gt;90 cm/s met criteria for vasospasm in the posterior circulation (criterion C). In the MCA, 45.5% of patients developed vasospasm based on criterion A and 36.3% developed vasospasm based on criterion B. A total of 18.2% of patients developed vasospasm in the BA by criterion C. Typical day of onset of vasospasm was hospital day 2–3. Duration of vasospasm in the anterior circulation was 4 ± 2 days based on criteria A and 3 ± 1 days based on criteria B. Vasospasm in the posterior circulation persisted for 2 ± 1 days. Using the adult criteria outlined above to diagnose vasospasm, a significant proportion of pediatric patients who have suffered moderate to severe traumatic brain injury develop vasospasm during the course of their treatment

Ischemic stroke as a complication of cryptococcal meningitis and immune reconstitution inflammatory syndrome: a case report.

BACKGROUND: Cryptococcal meningitis remains the leading cause of adult meningitis in Sub-Saharan Africa. Immune Reconstitution Inflammatory Syndrome (IRIS) following anti-retroviral therapy (ART) initiation is an important complication. Here we report the first documented case of a IRIS reaction presenting as an ischemic stroke. CASE PRESENTATION: A 38 year old newly diagnosed HIV-infected, ART naive Malawian male presented to a tertiary referral hospital in Blantyre, Malawi with a 2 week history of headache. A diagnosis of cryptococcal meningitis was made and the patient was started on 1200 mg fluconazole once daily and flucytosine 25 mg/kg four times daily as part of the Advancing Cryptococcal Treatment for Africa (ACTA) clinical trial. There was an initial clinical and microbiological response to anti-fungal treatment and anti-retroviral therapy was started at week 4. The patient re-presented 16 days later with recurrence of headache, fever, and a sudden onset of left sided weakness in the context of rapid immune reconstitution; peripheral CD4 count had increased from a baseline of 29 cells/μl to 198 cells/μl. Recurrence of cryptococcal meningitis was excluded through CSF examination and fungal culture. Magnetic Resonance Imaging (MRI) of the brain demonstrated multi-focal DWI (diffusion weighted imaging) positive lesions consistent with an ischemic stroke. Given the temporal relationship to ART initiation, these MRI findings in the context of sterile CSF with raised CSF protein and a rapid immune reconstitution, following an earlier favorable response to treatment is most consistent with a paradoxical Immune Reconstitution Inflammatory Syndrome. CONCLUSIONS: Stroke is an increasing cause of morbidity and mortality amongst HIV infected persons. Ischemic stroke is a recognized complication of cryptococcal meningitis in the acute phase and is thought to be mediated by an infectious vasculitis. This is the first time an ischemic stroke has been described as part of a paradoxical IRIS reaction. This report adds to the spectrum of clinical IRIS presentations recognized and highlights to clinicians the potential complications encountered at ART initiation in severely immunocompromised patients

Sequence analysis of the Epstein-Barr virus (EBV) BRLF1 gene in nasopharyngeal and gastric carcinomas

<p>Abstract</p> <p>Background</p> <p>Epstein-Barr virus (EBV) has a biphasic infection cycle consisting of a latent and a lytic replicative phase. The product of immediate-early gene BRLF1, Rta, is able to disrupt the latency phase in epithelial cells and certain B-cell lines. The protein Rta is a frequent target of the EBV-induced cytotoxic T cell response. In spite of our good understanding of this protein, little is known for the gene polymorphism of BRLF1.</p> <p>Results</p> <p>BRLF1 gene was successfully amplified in 34 EBV-associated gastric carcinomas (EBVaGCs), 57 nasopharyngeal carcinomas (NPCs) and 28 throat washings (TWs) samples from healthy donors followed by PCR-direct sequencing. Fourteen loci were found to be affected by amino acid changes, 17 loci by silent nucleotide changes. According to the phylogenetic tree, 5 distinct subtypes of BRLF1 were identified, and 2 subtypes BR1-A and BR1-C were detected in 42.9% (51/119), 42.0% (50/119) of samples, respectively. The distribution of these 2 subtypes among 3 types of specimens was significantly different. The subtype BR1-A preferentially existed in healthy donors, while BR1-C was seen more in biopsies of NPC. A silent mutation A/G was detected in all the isolates. Among 3 functional domains, the dimerization domain of Rta showed a stably conserved sequence, while DNA binding and transactivation domains were detected to have multiple mutations. Three of 16 CTL epitopes, NAA, QKE and ERP, were affected by amino acid changes. Epitope ERP was relatively conserved; epitopes NAA and QKE harbored more mutations.</p> <p>Conclusions</p> <p>This first detailed investigation of sequence variations in BRLF1 gene has identified 5 distinct subtypes. Two subtypes BR1-A and BR1-C are the dominant genotypes of BRLF1. The subtype BR1-C is more frequent in NPCs, while BR1-A preferentially presents in healthy donors. BR1-C may be associated with the tumorigenesis of NPC.</p

Role of fine-needle aspiration cytology and core biopsy in the preoperative diagnosis of screen-detected breast carcinoma

Core biopsy (CB) has now largely replaced fine-needle aspiration cytology (FNAC) in the preoperative assessment of breast cancer in the UK. We studied the contribution of FNAC and CB in the preoperative diagnosis of screen-detected breast carcinoma. Data were prospectively collected on 150 840 women who underwent breast screening over a 4-year period from 1999 to 2003. Data on women who had both FNAC and CB taken from the same lesion preoperatively and in whom surgical excision of the lesion subsequently confirmed malignancy was analysed. In 763 cancers, FNAC was inadequate (C1) in 8% and benign (C2) in 10%. Most of these cases presented with microcalcification (25% were C1 or C2). Core biopsy was not representative (B1) or benign (B2) in 7%. The absolute and complete sensitivities were 65 and 82% for FNAC and 80 and 93% for CB in the diagnosis of cancer. Core biopsy was abnormal (B3 or above) in 86% of the cancers missed by FNAC and FNAC was abnormal (C3 or above) in 65% of those missed by CB. Core biopsy is better than FNAC at preoperative diagnosis of screen-detected breast cancer as it missed fewer cancers. However, combining FNAC resulted in a better preoperative diagnosis rate
