Distribution Of Erm Proteins In The Stomach Mucosa Of Normal And Diabetic Rats, Asmaa Salem Al Sereidi Nov 2022

Distribution Of Erm Proteins In The Stomach Mucosa Of Normal And Diabetic Rats, Asmaa Salem Al Sereidi

Theses

Diabetes mellitus (DM), or simply diabetes, refers to a group of metabolic disorders that include a variety of diseases that disrupt our body's metabolism. The long-term uncontrolled disease can lead to stomach complications such as gastroparesis, as well as disruption in several proteins, such as ERM (Ezrin, radixin, moesin) proteins. ERM proteins are three proteins that are structurally and functionally related. ERM proteins have molecular masses of 82, 80, and 75 kDa, respectively. Ezrin is highly expressed in the stomach, especially in parietal cells that secrete gastric acid. ERM proteins function as scaffolding proteins in lipid rafts and granule trafficking …

Assessing The Impact Of Lipopolysaccharide On Learning And Memory In Rats, Anahat Luthra Aug 2022

Assessing The Impact Of Lipopolysaccharide On Learning And Memory In Rats, Anahat Luthra

Undergraduate Student Research Internships Conference

The immune system and the central nervous system (CNS) have a bi-direction relationship, modulating one another.4 Proinflammatory cytokines released from CNS immune cells have an impact on cognitive processes such as learning and memory.1 Liposaccharide (LPS), a cell wall component of Gram-negative bacteria, which is used to activate proinflammatory cytokine release has been found to impact learning and memory processes, such as in the anticipatory nausea paradigm (ANP).2 Anticipatory nausea and vomiting is that which may occur before a chemotherapy treatment session begins in a patient who has had chemotherapy before. It is caused by triggers like …

The Association Between Fgf21 And Diabetic Erectile Dysfunction: Evidence From Clinical And Animal Studies, Song Yang, Yichun Zhang, Xiaohui Lyu, Yuanyuan Gu, Guodong Zhang, Pengcheng Liu, Yulu Zheng, Zheng Guo, Yanbo Zhang, Haifeng Hou

Research outputs 2022 to 2026

Erectile dysfunction (ED), a complication of diabetes mellitus (DM), affects 50–75% of men with diabetes. Fibroblast growth factor 21 (FGF21) is a liver-derived metabolic regulator which plays a role in insulin-independent glucose uptake in adipocytes. We designed a clinical study and an animal experiment to investigate the relationship between FGF21 and DM-induced ED. The clinical study enrolled 93 participants aged > 18 years (61 patients with type 2 DM and 32 healthy controls) from Taian City Central Hospital (TCCH) in Shandong Province, China, amongst whom the association between serum FGF21 and diabetic ED was analyzed. To further validate this association, we …

Pituitary Adenylate Cyclase-Activating Polypeptide Receptor Activation In The Hypothalamus Recruits Unique Signaling Pathways Involved In Energy Homeostasis, Brian Maunze, Katherine Wood Bruckner, Nikhil Nilesh Desai, Christopher Chen, Fanghong Chen, David Baker, Sujean Choi Mar 2022

Pituitary Adenylate Cyclase-Activating Polypeptide Receptor Activation In The Hypothalamus Recruits Unique Signaling Pathways Involved In Energy Homeostasis, Brian Maunze, Katherine Wood Bruckner, Nikhil Nilesh Desai, Christopher Chen, Fanghong Chen, David Baker, Sujean Choi

Biomedical Sciences Faculty Research and Publications

Pituitary adenylate cyclase activating polypeptide (PACAP) exerts pleiotropic effects on ventromedial nuclei (VMN) of the hypothalamus and its control of feeding and energy expenditure through the type I PAC1 receptor (PAC1R). However, the endogenous role of PAC1Rs in the VMN and the downstream signaling responsible for PACAP’s effects on energy balance are unknown. Numerous studies have revealed that PAC1Rs are coupled to both Gαs/adenylyl cyclase/protein kinase A (Gαs/AC/PKA) and Gαq/phospholipase C/protein kinase C (Gαq/PLC/PKC), while also undergoing trafficking following stimulation. To determine the endogenous role of PAC1Rs and downstream signaling that may explain PACAP’s pleiotropic effects, we used RNA interference …

Effects Of Different Scar Types On Flap Viability In A Skin Flap Model: An Experimental Study, Ceyhun Uzun, Can İlker Demi̇r, Emrah Kağan Yaşar, Mehdi̇ Asadov, Murat Şahi̇n Alagöz, Esra Ci̇vri̇z, Çi̇ğdem Vural Jan 2022

Effects Of Different Scar Types On Flap Viability In A Skin Flap Model: An Experimental Study, Ceyhun Uzun, Can İlker Demi̇r, Emrah Kağan Yaşar, Mehdi̇ Asadov, Murat Şahi̇n Alagöz, Esra Ci̇vri̇z, Çi̇ğdem Vural

Turkish Journal of Medical Sciences

Background/aim: The purpose of this study was to investigate the use of tissues with multiple traumas, scarred pedicles, and medial scarring as a flap. Materials and methods: Forty-eight rats were randomly divided into four equal groups. The modified McFarlane flap was chosen as the flap model. In Group 1 (control), a dorsal skin flap was elevated and then sutured back into original position. In the other groups, a two-phase procedure was used. In Group 2 (pedicle incision), scar tissue was created with a skin incision at the prospective pedicle site of the flap and then sutured to its original site. …

Pathological And Immunohistochemical Changes In The Liver Of Monocrotaline-Treated Rats, Şevket Soylu, Aydin Çevi̇k, Necati̇ Ti̇murkaan Jan 2022

Pathological And Immunohistochemical Changes In The Liver Of Monocrotaline-Treated Rats, Şevket Soylu, Aydin Çevi̇k, Necati̇ Ti̇murkaan

Turkish Journal of Veterinary & Animal Sciences

Pathological and immunohistochemical changes in livers were investigated in monocrotaline-treated rats. Eighty adult-male Wistar rats were distributed in 5 groups, each containing 16 animals according to monocrotaline dose (Group I: 50 mg/kg, Group II: 100 mg/kg, Group III: 150 mg/kg, and Group IV: 200 mg/kg). The control group was administered with physiological saline. Half of the animals in each group were euthanized at the 18th hour while the remaining half at the 6th week postinoculation. At the end of the 18th hour, the most prominent lesion was hepatocytic apoptosis which was dose-dependent. Apoptotic cells were mostly located in periportal and …

Circulating Mir-200c And Mir-33a May Be Used As Biomarkers For Predicting High Fructose Corn Syrup-Induced Fatty Liver And Vitamin D Supplementation-Related Liver Changes, Alpaslan Tanoğlu, Eylem Çağiltay, Esra Güzel Tanoğlu, Ayli̇n Gökhan, Cansin Şi̇ri̇n, Türker Çavuşoğlu, Recep Soner Yeşi̇lbaş Jan 2022

Turkish Journal of Medical Sciences

Background/aim: Nonalcoholic fatty liver is one of the most common forms of liver disease and role of microRNAs (miRNAs) on this illness is currently unclear. It was aimed to evaluate the predictive role of circulating miR-33a and mir-200c on high fructose corn syrup (HFCS)-induced fatty liver and vitamin D3 supplementation-related hepatic changes. Materials and methods: Twenty-four rats were randomized into three groups: sham (n = 8), experimental fatty liver group (n = 8), and fatty liver + vitamin D3 supplementation group (n = 8). In the treatment group, 10 µg/kg/week of vitamin D3 was given by orogastric tube weekly for …
