Background: Traumatic brain injuries cause damages in the brain in several ways, which include cell death because of edema, disruption of the blood-brain barrier, shear stress, and ischemia. In this study, we investigated the effects of adrenomedullin (AM) on oxidative stress and inflammation after head traumas in a rat model.

Methods: Eighteen male adult Wistar albino rats were randomized into three groups (n=6).

The aim of this study was to evaluate the effects of tubal ligation (TL) via modified Pomeroy method on ovarian reserve and to determine the role of curcumin (Curcuma longa [Indian saffron]) against ovarian reserve decrement after TL. Forty-eight albino Wistar rats were randomly divided into four groups: (1) Control group: a sham operation was performed (n = 12), (2) Tubal ligation group: TL was performed (n = 12), (3) TL+DMSO group: 1 mL/day dimethyl sulfoxide was used for 50 days after TL, (4) TL+Curc group: 100 mg/kg/day curcumin dissolved in DMSO was administrated for 50 days after TL. Pre-operatively and on post-operative day 50, blood samples were collected for AMH evaluation, and oophorectomy was performed for histological and immunohistochemical examinations of ovaries in all groups.

Article Synopsis
  • Intestinal ischemic reperfusion injury (IRI) poses significant clinical challenges due to high rates of morbidity and mortality, prompting research into therapeutic options like vascular endothelial growth factor (VEGF).
  • The study assessed the local effectiveness of VEGF in relation to its application timing during IRI in an experiment with 30 Wistar albino rats, comparing groups receiving VEGF at different stages of the injury process.
  • Results showed that both early and late VEGF applications reduced harmful inflammation markers and improved overall intestinal health, with the best outcomes observed when VEGF was administered just before ischemia.

Purpose: To investigate the relationship between inflammation in the vitreous and diabetic retinopathy.

Methods: Vitreous samples from 21 patients with proliferative diabetic retinopathy (PDR), 21 patients with nonproliferative diabetic retinopathy (NPDR), and 21 nondiabetic patients with idiopathic epiretinal membranes (control) were studied. The interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), matrix metalloproteinase (MMP)-2, MMP-9, and adiponectin levels in the vitreous were detected in all samples with enzyme-linked immunosorbent assay (ELISA).

Background: Diabetic retinopathy is one of the most common eye diseases faced by diabetic patients. It is a slow-progressing complication that results from damage to the blood vessels of the retina.

Objectives: To investigate the role of adiponectin and inflammatory cytokines in the vitreous of diabetic rats.

Objective: In adults and children, the duration of chemotherapy-induced neutropenia and associated complications has decreased because of the prophylactic use of granulocyte colony-stimulating factors (G-CSFs). Biosimilar G-CSFs can play an important role in reducing treatment costs in daily practice. However, some concerns regarding the efficacy and safety of new biosimilar products exist among clinicians.

Background: Ischemia reperfusion injury is unavoidable in the setting of transplantation and may lead to primary dysfunction of the transplanted organ. Similarly, intestinal ischemia reperfusion injury may have deleterious effects causing intestinal failure. Montelukast is a selective reversible cysteinyl-leukotriene type 1 receptor antagonist used in clinical practice for its anti-inflammatory effects.

Diabetic patients suffer from persistent and non-healing wounds. Salvia species are traditionally used for the treatment of wounds and colds. The aims of the present study were to evaluate the in vivo wound healing potential, in vitro antimicrobial and antioxidant activities, and total phenolic and flavonoid contents of the aerial parts of two endemic taxa, Salvia kronenburgii Rech.

Background: Flavonoids have previously been suggested to play a role in wound healing. To date, however, limited information is available on the wound healing effect of kaempferol (KM), which belongs to the class of flavonoids. The objective of this study was to determine the wound healing effects of KM.

Objective: Spinal cord injuries generate the most negative response to medical treatment among all general body injuries. This important morbidity is thought to be caused by a complex secondary damage mechanism. In the present study, we examined the neuroprotective effects of alemtuzumab in a spinal cord trauma model.

Use of direct composite and indirect laminate veneers has been an alternative to metal- and all-ceramic crowns for anterior teeth restorations. Dental traumas are the most common reasons for excessive tissue loss. Treatment options depend on the amount of remaining tissue, the extent of the damage to dental pulp and periapical tissues and the time elapsed before dental treatment.

Background: Dental injuries are frequently occurred by an impact to facial area among basketball players. In fact, mouthguards are able to absorb the power of impacts and protect teeth from excessive forces, it is crucial for players even at training to wear mouthguards. To determine the prevalence of dental injuries and investigate the awareness about the use of mouthguards among basketball players and coaches.

Transcobalamin deficiency (OMIM 275350) is a rare autosomal recessive disease presenting with nonspecific clinical features in early infancy. We report the clinical and laboratory manifestations of 7 children diagnosed with transcobalamin deficiency. All patients were admitted between 2 and 4 months of age with anemia, thrombocytopenia, and hyperhomocysteinemia.

Background: This study investigated the effects of an amino acid mixture containing arginine, glutamine, and β-hydroxy-β-methyl butyrate on secondary healing of ischemic wounds in a rat model (N = 18).

Methods: After the formation of a bipediculated flap on each rat, 2 full-thickness excisional skin wounds (2 × 2 cm) were created on every flap. The rats were then randomized into the control and treatment groups.

Background: Wound healing is a complex process, dependent on available nutrition substrates. When used together with β-hydroxy β-methylbutyrate, arginine and glutamine have been shown to increase collagen deposition in human subjects. However, there are no experimental investigations on the influence of this amino acid mixture with regard to secondary wound healing.
