Efficacy and safety of glucagon-like peptide 2 in patients with short bowel syndrome: a systematic review and network meta-analysis.

Background: Glucagon-like peptide 2 (GLP-2) is a highly conserved enteroendocrine hormone that seems to be a regulator promoting intestinal adaptation. This study aimed to summarize the evidence on the efficacy and safety of exogenous GLP-2 in patients with short bowel syndrome (SBS).

Methods: A database search was performed on PubMed, Web of Science Core Collection, Scopus, Ovid, and the Cochrane Central Register of Controlled Trials in November 2022.

Will Nigella sativa oil protect parotid glands of rats against cranium gamma irradiation? Histological and immunohistochemical evaluation.

Background: Radiation plays an essential role in treating malignancies. Radiation exposure of salivary glands often results in permanent loss of their functions; therefore, their protection against radiation is crucial. Nigella sativa oil (NSO) is a useful antioxidant against free radicals.

The efficacy of using metformin and/or quercetin for amelioration of gamma-irradiation induced tongue toxicity in diabetic rats.

Background: Diabetes is a common disease that cancer patients may suffer from and may aggravate side effects of radiotherapy. This study aimed to detect whether metformin and/or quercetin will improve gamma-irradiation induced tongue toxicity in diabetic rats.

Methods: 35 male albino rats were divided into five groups; NOR no streptozotocin, no radiation and no treatment was given, DR rats were subjected to streptozotocin then gamma-irradiation, DRM rats were subjected to streptozotocin then gamma-irradiation then metformin, DRQ rats were subjected to streptozotocin then gamma-irradiation then quercetin, DRMQ rats were subjected to streptozotocin then gamma-irradiation then metformin and quercetin.

Vitamin E ameliorates oral mucositis in gamma-irradiated rats (an in vivo study).

Background: Radiation therapy is the primary treatment for neck and head cancer patients; however, it causes the development of oral mucositis accompanied by tissue structure destruction and functional alteration. This study was conducted to evaluate the effect of different doses of vitamin E as a treatment for radiationinduced oral mucositis in rat model.

Methods: 35 male albino rats were randomly divided into five groups: control, untreated radiation mucositis (single dose of 20 Gy), treated radiation mucositis; radiation (single dose of 20 Gy) then vitamin E at doses of 300, 360 and 500 mg/Kg for seven days started 24 h after irradiation.

Histomorphometric Analysis of the Healing Capacity of Low-Level Laser on Thermally Induced Tongue Ulcers for Gamma-Irradiated Rats.

This study aimed to assess the efficacy of low-level laser therapy (LLLT) for treating thermal tongue ulcers in gamma-irradiated rats. Postradiotherapeutic trauma may cause cell death, tissue damage, organ dysfunction, and loss of hematological components. Thermal ulcers were induced on the dorsal surfaces of tongues of gamma-irradiated rats (15 Gy).

Parents' perception of COVID-19 risk of infection and intention to vaccinate their children.

Background: Parent's perception of the COVID-19 vaccines is very important to protect themselves and their children and achieve maximum effect of vaccination programs.

Objective: Evaluate the perception and attitude of parents towards COVID-19 risk of infection and intentions to vaccinate their children.

Method: Cross-sectional study including 1032 participants who have children aged from 5 to 18 years using a structured questionnaire.
