Ethosuximide: Subunit- and Gβγ-dependent blocker and reporter of allosteric changes in GIRK channels.

Background And Purpose: The antiepileptic drug ethosuximide (ETX) suppresses epileptiform activity in a mouse model of GNB1 syndrome, caused by mutations in Gβ protein, likely through the inhibition of G-protein gated K (GIRK) channels. Here, we investigated the mechanism of ETX inhibition (block) of different GIRKs.

Experimental Approach: We studied ETX inhibition of GIRK channels expressed in Xenopus oocytes with or without their physiological activator, the G protein subunit dimer Gβγ.

Rare Coexistence: Giant Cell Tumor Recurrence and Infection in the Proximal Tibia - A Case Report.

Introduction: Giant cell tumor of bone (GCTB) ranks among the most prevalent locally aggressive tumor lesions, displaying a diverse range of biological behaviors. Recurrence of GCTB is well-documented, often attributed to microscopic tumour remnants remaining after intralesional curettage, with increased concern when infection occurs postoperatively. Studies suggest the limited effectiveness of adjuvants in preventing giant cell tumour recurrence, emphasizing the necessity of complete removal of malignant cells.

Can unilateral-transforaminal lumbar interbody fusion replace the traditional transforaminal lumbar interbody fusion procedure for lumbar degenerative disc diseases?: a single center matched case-control mid-term outcome study.

Study Design: Matched case-control study.

Purpose: To evaluate the midterm outcomes of unilateral pedicle screw fixation (UPSF) versus bilateral pedicle screw fixation (BPSF) in transforaminal lumbar interbody fusion (TLIF) procedure, ascertain efficacy of UPSF in adequately decompressing contralateral foramen+spinal canal and reducing rate of adjacent segment degeneration (ASD) at 4-8-year follow-up (FU).

Overview Of Literature: Previous meta-analyses found no significant differences between UPSF and BPSF regarding fusion rates, clinical and radiological outcomes; however, few studies have reported higher rates of cage migration/subsidence and pseudoarthrosis in the UPSF.

Spontaneous multiple keloids: a case report.

An aberrant healing reaction to cutaneous injury or inflammation that spreads outside the original wound's boundaries causes keloidal scars. We present the case of a sixty-year-old male patient who initially came with complaints of respiratory system but had spontaneous lesions over his body for 50 years which remained undiagnosed. It was confirmed on histological examination to be keloids.
