Background: In the last two years, due to the impact of COVID-19, students were forced to continue their education online because the government imposed restrictions to limit the spread of the virus. However, with the resumption of offline classes, the students seem to be suffering more from stress and isolation as they must face the challenges of the real world, which are quite different from the virtual one to which they have become accustomed. In this study, the effect of stress on students leading to their academic burnout and the influence of burnout on their learning satisfaction was studied.

Chemotherapeutic refractoriness of advanced cutaneous melanoma may be linked with melanoma-initiating cells, also known as melanoma stem cells. This study aimed to determine relative risk of clonal dominance of the CD133+ phenotype in tissues from melanoma patients with different clinical outcomes that could be applied to early diagnosis, prognosis or disease monitoring. Significant overexpression of CD133 (p<0.

Background: Human cutaneous melanoma can be one of the most aggressive tumors and is extremely resistant to all current therapeutic modalities. Immunohistochemistry (IHC) studies were undertaken to assess independent relative frequency on preferential overexpression and simultaneous expression of four stem cell markers; CD133+, ABCB5+, CD166, and Nestin, at different stages of the disease.

Material And Methods: Five-micron sections from paraffin blocks from primary melanoma, lymph node (LN) metastases, distant metastases, benign nevi from non-melanoma patients (NMP), and patients with past history of melanoma (MP) were IHC stained with monoclonal antibodies (mAb) to the four stem cell markers.

Cytokines and growth factors have biologic effects that could stimulate tumor growth, invasion and angiogenesis. The incidence of 24 factors was investigated in 25 cultured human melanoma cell lines and in 62 fixed tissues at different stages of the disease. Over 80% of the human melanoma cell lines expressed TGF-β, IL-8, IL-6, VEGF, PDGF-AA and OPN.

A review of the natural behavior of cutaneous melanoma, clinical and pathological factors, prognostic indicators, some basic research and the present and possible futuristic strategies in the management of this disease are presented. While surgery remains to be the most effective therapeutic approach in the management of early primary lesions, there is no standard adjuvant therapy after surgical resection, or for metastatic disease.

The study of history of medical science from non-medical sources needs no apology. At first the discussion of what was thought in the past rather than what is known now appears to be of merely antiquarian value. The knowledge of Diet, Dietetics, medicinal plants dates back to the remote antiquity of mankind.

Herpes simplex virus type 2 (HSV-2) genes expressed in neuronal cells in response to stress stimuli that trigger latency reactivation are largely unknown. Using a chloramphenicol acetyltransferase (CAT) reporter assay we found that stress caused a significant (P < .001) increase in ICP10 expression in neuronal cells.

Herpes simplex virus (HSV)-associated erythema multiforme (HAEM) is a recurrent disease characterized by the presence and expression of HSV DNA fragments in lesional skin. Our studies examined the mechanism of viral DNA transport to the skin of HAEM patients. CD34+ cells were isolated from the blood of normal subjects and HSV and HAEM patients during acute lesions and at quiescence.

Breast cancer tissues from 271 cases were analyzed immunologically for c-erbB-2 oncoprotein (HER-2/neu), epidermal growth factor receptor (EGF-R) and estrogen receptor (ER). Overexpression of both c-erbB-2 oncoprotein and EGF-R showed an inverse association with ER and a direct association with metastatic involvement of lymph node and high histological grade. The frequency of c-erbB-2 and EGF-R overexpression was significantly higher among postmenopausal cases in comparison with premenopausal cases.
