Variations in 5HT-related genes contribute to the alterations of serotonergic neurotransmission, which is implicated in the etiopathology of alcoholism. In this preliminary study we have tested polymorphisms of genes involved in 5HT transport and turnover for their association with alcohol dependence. A case group of males with type 2 alcoholism (N=59) and a control group of healthy males (N=282), both of Croatian origin, were analyzed for the frequency distribution of polymorphisms in 5HT transporter (5HTT-VNTR2, 5HTT-LPR), monoamine oxidase A (MAOA-uVNTR) and B (MAOB-A/G) and tryptophan hydroxylase 1 (TPH1 A218C) and 2 (TPH2 G-703T) genes. An increase in the frequencies of 10-repeat allele (p = 0.010; OR = 1.73; 95% CI = 1.14-2.60) and 10/10 genotype (p = 0.006; OR = 2.57; 95% CI = 1.32-5.00) of the 5HTT-VNTR2 polymorphism was found in alcoholic patients. No differences between case and control groups were observed for the other tested polymorphisms. Present results support earlier studies implicating the role of 5HTT gene in alcoholism. The increase of sample size (in progress) is expected to enable search of more subtle differences, as well as re-evaluation of these preliminary findings.

Distal tibial fractures are common lower-limb injuries and are generally associated with a high risk of postoperative complications, especially in patients with multiple medical comorbidities. This study sought to ascertain the efficacy of retrograde intramedullary tibial nails (RTN) for treating extra-articular distal tibial fractures in high-risk patients. Between January 2019 and December 2021, 13 patients considered at high risk for postoperative complications underwent RTN fixation.

With a rising incidence in an aging population, controversy surrounds surgical versus nonoperative treatments, particularly for displaced 3- and 4-part fractures in older patients. Locking plates (LP) and proximal intramedullary nails (PHN) are primary choices for surgical intervention, but both methods entail complications.

The smoky scent is the most distinctive feature for Souchong black tea. To reduce the dependence on pinewood in the smoking process of Souchong black tea, it is crucial to find an effective alternative smoking material. Five black tea samples were prepared via using specially designed fuel rods as the smoking material in this study.

Recent research has identified sex-dependent links between risk taking behaviors, approach-avoidance bias and alcohol intake. However, preclinical studies have typically assessed alcohol drinking using a singular dimension of intake (i.e.

Cuproptosis, a copper-dependent form of regulated cell death, has been implicated in the progression and treatment of various tumors. The copper ionophores, such as Disulfiram (DSF), an FDA-approved drug previously used to treat alcohol dependence, have been found to induce cuproptosis. However, the limited solubility and effectiveness of the combination of DSF and copper ion restrict its widespread application.
