Associations regarding Dietary Design as well as Snooze Period together with Intellectual Decline in Community-Dwelling Older Adults: A new Seven-Year Follow-Up Cohort Study.
4±0.98 mV. AgNPs-EC had an inhibitory effect on cytokine mRNA and protein expression levels, which suggests that they could be used safely in the fight against cancer. AgNPs-EC cytotoxicity was also found to be non-toxic to MCF-7.

Our data determined AgNPs-EC as a novel inhibitor of TNF-α production. These results are promising for developing novel therapeutic approaches for the future treatment of cancer with safe materials.

Pulmonary hypertension (PH) is a pathological process mainly characterized by the progressive increase in pulmonary vascular resistance. The degradation of pulmonary artery smooth muscle cells (PASMCs) from contractile/differentiated phenotype to synthetic/dedifferentiated phenotype is a key factor for hypoxic pulmonary hypertension.

In this study, qPCR was performed to evaluate the gene expression of mRNAs. Western blot, immunofluorescence and RNA pull down were used to detect gene expression levels.

We found that the gene expression of polypyrimidine tract-binding protein1 (PTBP1) was increased significantly in a time-dependent manner in rats PA tissues and PASMCs after hypoxia. PTBP1 knockdown can inhibit the phenotypic transition of PASMCs. PTBP1 inhibits the phenotypic transition of PASMCs. In addition, PTBP1 inhibits the integrin-linked kinase (ILK) expression under hypoxic conditions, thereby down-regulating the expression of downstream proteins. It inhibits the phenotypic transition of PASMCs and alleviates pulmonary hypertension.

In conclusion, PTBP1/ILK axis promotes the development of PH via inducing phenotypic transition of PASMCs. This may provide a novel therapy for PH.

Recent evidence has highlighted the anti-inflammatory properties of the constituent of Green Tea Polyphenols (GTP), epigallocatechin-3-gallate (EGCG) which has been suggested to exert a neuroprotective effect on Alzheimer's disease (AD). The current study aimed to elucidate the effect of EGCG on memory function in rats with AD.

AD rat models were initially established through an injection with Aβ 25-35 solution, followed by gavage with EGCG at varying doses to determine the effect of EGCG on learning and cognitive deficits in AD. Morris water maze test was conducted to evaluate the spatial memory function of the rats. Immunohistochemistry and Western blot analysis were performed to identify Tau phosphorylation. The expression of β-site amyloid precursor protein-cleaving enzyme 1 (BACE1) mRNA and protein in rat hippocampus was measured by reverse transcription quantitative polymerase chain reaction (RT-qPCR) and Western blot analysis. Acetylcholinesterase (AchE) activity, Aβ1-42 expression and Ach content were all detected using enzyme-linked immunosorbent assay (ELISA).

EGCG intervention brought about a decrease in the escape latency period while increasing the time at the target quadrant among the AD rats. EGCG decreased the hyperphosphorylation of Tau in hippocampus. BACE1 expression and activity as well as the expression of Aβ1-42 were suppressed by EGCG. Moreover, EGCG promoted Ach content by diminishing the activity of AchE.

The current study demonstrates that EGCG may diminish the hyperphosphorylation of the Tau protein, downregulate BACE1 and Aβ1-42 expression to improve the antioxidant system and learning and memory function of rats with AD.

Very few treatments, however, have been approved by the Food and Drug Administration for the treatment of bipolar depression. Cariprazine, a broad-spectrum dopamine antagonist/partial agonist with dopamine D3/D2 (preferring D3) and serotonin 5-HT1A receptor partial agonist properties, was recently approved. A review of the literature suggests that it is an effective and well-tolerated treatment for bipolar depression.
To assess attitudes of pre-clinical undergraduate medical students toward learning smartphone funduscopy (SF) and its appropriateness as a teaching tool.

Second year medical students received instruction on direct ophthalmoscopy (DO) and SF; they were then paired with a peer and randomly assigned to perform DO or SF first. The SF technique involved freehand alignment of the axes of the smartphone camera with a condenser lens. Both techniques were done through a maximally dilated pupil. A questionnaire was completed to acquire data on baseline experience, performance of both examination techniques, attitudes, and appropriateness. Statistical significance testing and Bland-Altman analysis were used to determine differences between DO and SF, and a multivariable mixed regression model was fitted to identify any predictors for positive attitudes toward DO or SF.

One hundred thirty-seven (137) individuals completed the study. A similar proportion of students could identify the optic nerve, macula, and vesselechnique to DO in identifying structures. Despite overall favorable attitudes towards the more familiar DO, those students who quickly learned the SF technique had similar satisfaction scores. Teaching SF should be considered in undergraduate medical education.The clinical dilemma of management of isolated contralateral axillary metastasis (CAM) in carcinoma breast remains unsolved. We report a case of metachronous contralateral left axillary metastasis in a 54-year-old postmenopausal woman, its management, and review of literature. After ruling out distant metastasis and occult primary in the opposite breast, curative treatment was planned. She underwent left axillary lymph node dissection which on histopathology showed metastatic carcinoma. Management of CAM with curative or palliative intent and whether to consider them as locoregional or distant metastasis remains controversial. 3,4-Dichlorophenyl isothiocyanate CAM may occur due to the locoregional spread of disease, and hence, curative intent of treatment should be offered to these patients.Apart from iatrogenic causes, many of the foreign bodies in the bladder and urethra are self-inserted through the urethra as a result of psychiatric disturbances, sexual gratification, or erotic curiosity while intoxicated. Despite the reports on the presentation of urethrovesical foreign bodies in the medical literature, the insertion of foreign bodies through the urethra for the purpose of erotic satisfaction remains an enigma. Here, we report a case of a knotted earphone jack as an urethrovesical foreign body inserted for erotic reason by a 32-year-old man with no history of psychiatric disturbances. He could not retrieve it, and the bladder foreign body remained in this position for about 8 h. He was referred to the accident and emergency unit of our hospital, and open surgery was performed to retrieve it.Paraduodenal hernias are of congenital origin and may present with symptoms and signs of small intestinal obstruction. These hernias are rare in our practice, and a definitive preoperative diagnosis is often not made as the symptoms are not specific. Early assessment and prompt and adequate resuscitation and surgery obviate the risk of strangulation and intestinal resection. This report highlights a rare cause of intestinal obstruction in a young male who presents with all the classical features of obstruction colicky abdominal pain, distension, vomiting, and inability to pass stool or flatus. The diagnosis of paraduodenal hernia was made intraoperatively. We do not routinely request for barium examination or abdominal computed tomography scan in acute abdominal pain. These modalities can suggest a preoperative diagnosis.Schwannomas are the most common benign tumors of peripheral nerves but are rare in adults. They have an extremely slow rate of growth before the onset of symptoms such as pain, paresthesia, and tingling. Giant schwannomas of the extremities can significantly affect the quality of life. With a correct diagnosis, the tumor can be extirpated with preservation of nerve function and a very low risk of recurrence. A case of a symptomatic giant schwannoma on thenar eminence of the right hand in an adult male is discussed in this report.Interdigitating dendritic cell sarcoma (IDCS) is an extremely rare neoplasm arising from the antigen-presenting cells of the immune system. It usually involves the lymph nodes, and extranodal sites are rarely affected. Here, we report a first known case of spontaneous hemoperitoneum caused by the rupture of IDCS of the small bowel. A 61-year-old male presented with complaints of abdominal pain and fever for 3 days and breathlessness for 1 day. Ultrasound abdomen revealed a 15 cm × 7 cm heterogeneous collection with thick septations in the periumbilical region. Diagnostic peritoneal lavage revealed hemoperitoneum and gangrenous bowel. Emergency laprotomy was done and it revealed a friable mass arising from the ileum. Resection of 2 ft of the ileum and double-barrel ileostomy was done. Immunohistochemical analysis revealed a positivity of S100 and leukocyte common antigen). A diagnosis of IDCS was made. The patient had an uneventful postoperative recovery and planned for postoperative chemotherapy.A number of options exist for patients with anticipated difficult intubation on account of a retrosternal goiter compressing on the trachea. The chosen technique(s) to secure the airway in this delicate situation often depends on the location and degree of airway obstruction, available resources/facilities, and an anesthetist's experience and preferences. We report the case of a 68-year-old woman with severe airway obstruction from a retrosternal goiter coming for total thyroidectomy. Airway management started with an awake fiber-optic intubation, proceeded to a tracheostomy and finally to use of a rigid bronchoscope following failure of the earlier techniques to achieve adequate ventilation.Ectopic kidney is a congenital anomaly of renal position, which is commonly asymptomatic. Symptoms arising from pelvic kidneys can closely mimic pathological processes of nearby organs and vice versa. We report an 18-year-old girl who presented with acute onset of a painful lump in the right iliac fossa. Although the clinical features mimicked an appendicular abscess, the judicious use of cross-sectional imaging aided in the proper diagnosis. Pyonephrosis of a right-sided lumbar kidney was confirmed on further imaging and nephrectomy was performed. This case has been presented to highlight the significance of renal imaging in patients suspected of an appendicular abscess.The aim of this report is to highlight the challenges involved in the diagnosis and treatment of anal melanoma in a tertiary hospital in Nigeria. It is a case report of an 84-year-old man who was managed for anal malignant melanoma. Despite inadequate investigative tools and less radical surgical treatment, the survival period of the index patient was comparable to the median survival quoted in the literature. Despite its rarity, mucosal melanomas also occur in the tropics. Prompt diagnosis, adequate imaging, and standardized treatment may improve its outlook in the nearest future.
