Sewage analysis as an alternative tool for assessing drug of abuse and new psychoactive substances in Tunisia.

Many studies attest to the pollution of wastewaters by organic molecules including drug of abuse (DAs) residues and new psychoactive substances (NPS) at trace levels. The occurrence of these emerging micropollutants in influent wastewaters (IWW) from three Tunisian Wastewater Treatment Plants (WWTPs) was assessed. Influent wastewater composite samples (24 h) were collected over 7 consecutive days in November 2019.

Effects of lead, cadmium, copper and zinc levels on the male reproductive function.

This study aimed to investigate the effects of heavy metals on measures of male fertility.

Unusual Bladder Metastasis from a Primary Gastric Carcinoma: Two Case Reports and Review of Literature.

Primary bladder cancer is a frequent malignancy in the urology field, whereas secondary bladder neoplasms from a distant organ are extremely rare. This paper aims to report two rare cases of a secondary tumor of the urinary bladder from a primary gastric tumor and to perform a literature review of similar reported cases in order to better characterize its clinicopathological features and diagnosis in effort to shed light on this rare condition. The final diagnosis of secondary adenocarcinoma was made histologically after transurethral biopsy or resection of the bladder lesion.

A cadaveric anatomical study of the adrenals: Relationship with the posterior abdominal wall muscles revisited.

Aim Of The Study: The main difficulties during retroperitoneal laparoscopic adrenalectomies are due to its location. Our objective was to define the relationship of the adrenals with the diaphragm and the psoas muscle.

Methods: Our work is an anatomical dissection of 80 fresh cadavers' adrenals.
