Importance: Papillary thyroid microcarcinomas (PTMCs) have been associated with increased thyroid cancer incidence in recent decades. Total thyroidectomy (TT) has historically been the primary treatment, but current guidelines recommend hemithyroidectomy (HT) for select low-risk cancers; however, the risk-benefit ratio of the 2 operations is incompletely characterized.
Objective: To compare surgical complication rates between TT and HT for PTMC treatment.
Objective: To compare the outcome of harmonic scalpel use in thyroid surgery versus conventional suture method in a sample of Iraqi patients.
Methods: A prospective, comparative, interventional study with analytic elements was conducted on 76 patients complaining of different types of goitre attending Al-Yarmouk Teaching Hospital, Baghdad, from October 2017 to October 2019. Patients were divided into two groups, a test group including 25 patients operated upon by harmonic scalpel and the control group of 51 patients who underwent conventional suture ligation.
Using genetic tools to study the functional roles of molecularly specified neuronal populations in the primate brain is challenging, primarily because of specificity and verification of virus-mediated targeting. Here, we report a lentivirus-based system that helps improve specificity and verification by (a) targeting a selected molecular mechanism, (b) in vivo reporting of expression, and (c) allowing the option to independently silence all regional neural activity. Specifically, we modulate cholinergic signaling of striatal interneurons by shRNAmir and pair it with hM4Di_CFP, a chemogenetic receptor that can function as an in vivo and in situ reporter.
