- Study of Vitamin D Level and Vitamin D Receptor Polymorphism in Hypothyroid Egyptian Patients. [Journal Article]J Thyroid Res 2019; 2019:3583250JT
- CONCLUSIONS: This study confirmed the association of vitamin D deficiency with hypothyroidism, thyroid autoimmunity, increased volume, nodularity, and vascularity of thyroid gland in hypothyroid patients as well as increased HOMA-IR. It proved the association between HOMA-IR and thyroid autoimmunity. The study proved no association between VDR polymorphisms (Fok1 and Apa1) with either vitamin D levels or TSH levels.

- Association of circulating adipokine concentrations with indices of adiposity and sex in healthy, adult client owned cats. [Journal Article]BMC Vet Res 2019; 15(1):332BV
- CONCLUSIONS: Together our findings suggest that rather than gender, body weight and adiposity are more important determinants of circulating concentrations of the adipokines leptin and adiponectin. On the contrary, the adipokine omentin is not affected by body weight or adiposity but instead exhibits sexual dimorphism in cats.
- Duodenal pseudomelanosis (pseudomelanosis duodeni): a rare endoscopic finding. [Case Reports]Autops Case Rep 2011 Oct-Dec; 1(4):39-44AC
- Duodenal pseudomelanosis (or pseudomelanosis duodeni) is a rare benign condition characterized by black-brown speckled pigmentation of the duodenal mucosa. Collections of pigment-laden macrophages are found in the tips of duodenal villi. The pigment is thought to be mostly composed of ferrous sulfide. Histochemichal stains for iron (Perl's prussian blue) or melanin (Masson-Fontana) may be positiv…
Duodenal pseudomelanosis (or pseudomelanosis duodeni) is a rare benign condition characterized by black-brown speckled pigmentation of the duodenal mucosa. Collections of pigment-laden macrophages are found in the tips of duodenal villi. The pigment is thought to be mostly composed of ferrous sulfide. Histochemichal stains for iron (Perl's prussian blue) or melanin (Masson-Fontana) may be positive, but are usually negative or unpredictable. Duodenal pseudomelanosis occurs predominantly in middle-aged to old adults and more commonly in females. It is associated with chronic renal failure, arterial hypertension, diabetes mellitus and gastrointestinal bleeding. Medications such as ferrous sulfate, hydralazine, propranolol, hydrochlorothiazide and furosemide are thought to play a role as well. We report a case of a 86-year-old female who presented with a history of watery diarrhea and melena. The patient had a history of high blood pressure and ischemic stroke episodes. She was on multiple medication including hidralazine, captopril, hydrochlorthiazide and aspirin. She was dehydrated, her blood pressure was 96 × 60 mmHg and neurologic examination showed complete left hemiplegia with central VII nerve palsy. Laboratory tests showed normal serum electrolytes and renal function. Hemoglobin level was 10.7 g%. An upper endoscopy showed multiple diminutive black spots throughout the distal duodenal bulb and second portion. Histology showed multiple foci of a brown-black granular pigment inside macrophages within the tips of the villi (pseudomelanosis). Stains for iron and melanin were negative. She was treated with omeprazol, parenteral fluid replacement with saline and partial fasting. After complete recovery she was discharged for ambulatory follow up.
- [Effect of electroacupuncture on degradation of myosin heavy chain of gastrocnemius muscle in diabetes rats]. [Journal Article]Zhen Ci Yan Jiu 2019 Sept 25; 44(9):653-8ZC
- CONCLUSIONS: EA treatment can delay the atrophy of gastrocnemius muscle (skeletal muscle) in diabetes rats possibly by improving the degradation of myosin heavy chain via regulating the expression of muscular MuRF1, Fbxo32, Myh2, Myh4 and Myh7 mRNAs.
- Increased Serum Sedimentation and Positive Tuberculosis Antibody Combined Multiple Pulmonary Nodules in Chest CT in a Middle-Aged Patient Firstly Misdiagnosed as Tuberculosis Proved as Sarcoidosis by CT Guided Percutaneous Lung Puncture Biopsy: a Case Report and Literature Review. [Case Reports]Clin Lab 2019; 65(9)CL
- CONCLUSIONS: When a patient has multiple pulmonary nodules and lymphadenopathy without obvious tuberculosis poisoning symptoms, physicians should pay attention to tuberculosis, sarcoidosis, and lung cancer. Pathology is crucial for the ultimate diagnosis.
- Increased serum level and impaired response to glucose fluctuation of asprosin is associated with type 2 diabetes mellitus. [Journal Article]J Diabetes Investig 2019JD
- CONCLUSIONS: Serum asprosin level decreased coinciding with the onset of OGTT in NGT, wihle this circadian oscillation was disturbed in T2DM. The impaired response of asprosin to glucose fluctuation in T2DM might be one of reasons for the onset of T2DM.
- Distinct Metabolic Profile in Early Pregnancy of Overweight and Obese Women Developing Gestational Diabetes. [Journal Article]J Nutr 2019JN
- CONCLUSIONS: We identified a distinct early pregnancy metabolomic profile especially attributable to small HDL particles in women developing GDM. The aberrant metabolic profile could represent a novel way to allow early identification of this most common medical condition affecting pregnant women. This trial was registered at clinicaltrials.gov as NCT01922791.
- Effects of enalapril and paricalcitol treatment on diabetic nephropathy and renal expressions of TNF-α, p53, caspase-3 and Bcl-2 in STZ-induced diabetic rats. [Journal Article]PLoS One 2019; 14(9):e0214349Plos
- This study aimed to assess the renopreventive effect of enalapril and/or paricalcitol on streptozotocin (STZ) diabetes-induced nephropathy and to elucidate their mechanisms of action through investigation of the effects on renal oxidative stress, antioxidant defense system and expressions of TNF-α, p53, caspase-3, and Bcl-2.

This study aimed to assess the renopreventive effect of enalapril and/or paricalcitol on streptozotocin (STZ) diabetes-induced nephropathy and to elucidate their mechanisms of action through investigation of the effects on renal oxidative stress, antioxidant defense system and expressions of TNF-α, p53, caspase-3, and Bcl-2. Diabetes mellitus was induced in fasting male Wistar rats by single intraperitoneal injection of STZ (45 mg /kg b.w.) dissolved in citrate buffer (pH 4.5). Ten days after STZ injection, the diabetic rats were treated with enalapril (25 mg/l of drinking water) and/or paricalcitol (8 μg/kg b.w. per os) dissolved in 5% DMSO daily for 4 weeks. The obtained data revealed that the treatment of diabetic Wistar rats with enalapril and/or paricalcitol led to significant decreases in the elevated serum urea, uric acid, creatinine, sodium and potassium levels; thereby reflecting the improvement of the impaired kidney function. The deteriorated kidney lipid peroxidation, GSH content and GST and catalase activities in diabetic rats were significantly ameliorated as a result of treatment with enalapril and/or paricalcitol. The elevated fasting and post-prandial serum glucose levels and the lowered serum insulin and C-peptide levels were also improved. The treatment with enalapril and paricalcitol in combination was the most potent in decreasing the elevated serum glucose levels. Moreover, the treatment of diabetic rats successfully prevented the diabetes-induced histopathological deleterious changes of kidney and islets of Langerhans of pancreas. In association, the immunohistochemically detected pro-inflammatory cytokine, TNF-α, and apoptotic mediators, p53 and caspase-3, were remarkably decreased in kidney of diabetic rats as a result of treatment while the expression of anti-apoptotic protein Bcl-2 was increased. Based on these findings, it can be concluded that enalapril and paricalcitol alone or in combination can prevent STZ diabetes-induced nephropathy through amelioration of the glycemic state and antioxidant defense system together with the suppression of oxidative stress, inflammation and apoptosis. However, the treatment of diabetic rats with enalapril and paricalcitol in combination has no further significant improvement effects on renal function and damage when compared with enalapril or paclitaxel treated diabetic groups.
