Simultaneous Exposure to Noise and Toluene Induces Oxidative and Inflammatory Damage in the Heart of Wistar Rats: Therapeutic Potential of Olea europaea L. Leaf Extract.

Workers in occupational settings often face simultaneous exposure to multiple risk factors, including noise and chemicals. This study aimed to investigate the effects of combined exposure to noise and toluene on the cardiac health of rats, with a focus on assessing the potential mitigating effects of Olea europaea L. (OLE) leaf extract (40 mg/kg/day).

L. leaf extract mitigates pulmonary inflammation and tissue destruction in rats induced by concurrent exposure to noise and toluene.

This study aimed to investigate the effects of combined exposure to noise (85 dB(A)) and inhaled Toluene (300 ± 10 ppm) on rat lung health. It also aimed to assess the potential therapeutic effects of L. leaves extract (OLE) (40 mg/kg/day) using biochemical, histopathological, and immunohistochemical (IHC) analyses, as well as determination of pro-inflammatory cytokines (TNF-α and IL-1β), and Docking studies.

Acute respiratory distress syndrome: a life threatening associated complication of SARS-CoV-2 infection inducing COVID-19.

Acute Respiratory Distress Syndrome (ARDS) is a form of respiratory failure in human. The number of deaths caused by SARS-CoV-2 infection inducing this severe pneumonia (ARDS) is relatively high. In fact, COVID-19 might get worsen in ARDS and provoke respiratory failure.

Association of maternal homocysteine and vitamins status with the risk of neural tube defects in Tunisia: A case-control study.

Background: This study was conducted to determine whether low folate and vitamin B12 levels, as well as high homocysteine levels in pregnant women are associated with neural tube defects (NTDs) in Tunisia.

Methods: A total of 75 NTDs pregnancies and 75 matched controls were included in the study. Their vitamin B12, folate, and red blood cell folate concentrations were measured using a radio-immunoassay kit and total homocysteine concentrations were determined using a fluorescent polarization immunoassay.

An increase in spina bifida cases in Tunisia, 2008-2011.

Background: The term spina bifida refers to a group of neural tube defects that result in malformations of the spinal cord and the surrounding vertebrae. Though the etiologies of spina bifida remain largely unknown, several risk factors have been identified, including feto-maternal characteristics.

Aim Of The Study: To discover possible underlying reasons for the increase of spina bifida and identify intervention targets, an investigation was undertaken comparing spina bifida-affected pregnancy notifications in 2008-2011 with notifications in the period 1991-1994.

Epidemiology of neural tube defect subtypes in Tunisia, 1991-2011.

Background: Neural tube defects are common major congenital anomalies that result from very early disruption in the development of the brain and spinal cord.

Aim Of The Study: We conducted an epidemiological study to determine the impact of some feto-maternal characteristics in the occurrence of NTD subtypes.

Methods: Characteristics and outcomes of births with NTD and pregnancy characteristics of mothers over a period of twenty years (1991-2011) were recorded in the medical chart.

Walker 256/B malignant breast cancer cells disrupt osteoclast cytomorphometry and activity in rats: modulation by α-tocopherol acetate.

We examined the effects of vitamin E supplementation (VES) on osteoclast (OC) resorbing activity and cytomorphometry in Walker 256/B tumor osteolytic rats. Twenty-four aged male rats were randomized into 3 groups: 6 were sham operated; 9 were injected in the right hind limb with Walker 256/B cells (W256 group); and 9 were injected as above and supplemented with VE (45mg/kg BW) (W256VE group). Twenty days later, bone mass (BV/TV) and some microarchitectural parameters were assessed.
