High carbohydrate diet decreases microbial diversity and increases IL-1β levels in mice colon.

Western diet is known to contribute to intestinal dysbiosis and the progression of inflammation. Although the Turkish diet has different macronutrient contents, the intestinal inflammatory disease incidences in Türkiye are comparable to Western countries. Thus, we hypothesized that high carbohydrate diets also contribute to inflammation of the colon.

Effects of Modified Osteoplastic Pterional Craniotomy on Temporal Muscle Volume and Frontal Muscle Nerve Function.

 Pterional craniotomy is a surgical approach frequently used in aneurysm and skull base surgery. Pterional craniotomy may lead to cosmetic and functional problems, such as eyebrow drop due to facial nerve frontal branch damage, temporal muscle atrophy, and temporomandibular joint pain. The aim was to compare the postoperative effects of our modified osteoplastic craniotomy with classical pterional craniotomy in terms of any change in volume of temporal muscle and in the degree of frontal muscle nerve damage.

The management of xanthogranulomatous cholecystitis.

Objectives: Xanthogranulomatous cholecystitis (XGC) is a rare variant of chronic cholecystitis. This rare pathology is characterized by severe and progressive fibrosis of the gallbladder wall as well as infiltration of fat-laden macrophages.

Material And Methods: The final pathology report of 8213 cholecystectomies performed between 2011 and 2019 was evaluated retrospectively, and patients whose pathology result was reported as XGC were included in the study.

Tract pain because of cervical spondylotic myelopathy: A case series.

Spinal cord compression may lead to pain that is sometimes directed to areas far below the compression level. In certain cases, it may present as sciatica pain, knee pain or low back pain (LBP). These types of pain are called tract pain or funicular pain.

An innovative procedure: Laparoscopic sterilisation of liver hydatid cyst cavities with Foley catheter method.

Sterilisation of the liver hydatid cyst cavities is a significant step in the surgical treatment of these cysts. We previously performed a study addressing the Foley catheter method in sterilisation of the cyst cavities with open surgery. Recently, we have been laparoscopically using Foley catheters for sterilisation of the cyst cavities.

Withdrawn: An innovative procedure: Laparoscopic sterilization of liver cyst cavities with foley catheter method.

Brain-computer interface (BCI) is a technology used to convert brain signals to control external devices. Researchers have designed and built many interfaces and applications in the last couple of decades. BCI is used for prevention, detection, diagnosis, rehabilitation, and restoration in healthcare.

Lateral transorbital approach: an alternative microsurgical route for supratentorial cerebral aneurysms.

Objective: Transorbital approaches for neurosurgery have recently attracted attention and several anatomical studies have aimed to improve these techniques, but significant deficiencies in clinical practice remain, especially for aneurysm surgery. The authors present an alternative microsurgical route and the results of an analysis of patients with intracranial aneurysms who underwent a lateral transorbital approach (LTOA) using lateral orbito-zygoma-sphenotomy (LOZYGS).

Methods: The clinical and surgical results of a series of 54 consecutive patients with 1 or more aneurysms who underwent surgery via LTOA are reported.

Ketone Body Signaling Mediates Intestinal Stem Cell Homeostasis and Adaptation to Diet.

Little is known about how metabolites couple tissue-specific stem cell function with physiology. Here we show that, in the mammalian small intestine, the expression of Hmgcs2 (3-hydroxy-3-methylglutaryl-CoA synthetase 2), the gene encoding the rate-limiting enzyme in the production of ketone bodies, including beta-hydroxybutyrate (βOHB), distinguishes self-renewing Lgr5 stem cells (ISCs) from differentiated cell types. Hmgcs2 loss depletes βOHB levels in Lgr5 ISCs and skews their differentiation toward secretory cell fates, which can be rescued by exogenous βOHB and class I histone deacetylase (HDAC) inhibitor treatment.

A Simple Technique for Removing Broken Pedicle Screws.

Removing a broken pedicle screw is not always easy. Different methods and tools have been developed to remove the broken screw. Preserving the pedicle is an advantage for re-instrumentation.

Tegmento-vermian dysplasia: radiologic features of a novel described anatomic variation.

Here we present the incidental radiological findings of a case that has a huge pontine tegmental cap orienting posteriorly towards the fourth ventricle and continues with the inferior vermis, accompanied by a midline anterior midbrain cleft. Having knowledge about this variation will prevent a misdiagnosis of a posterior fossa tumor and eventual unnecessary biopsy or operation.

Do we need a transforaminal lumbar interbody fusion cage to increase the stability of functional spinal unit when comparing unilateral and bilateral fixation?

Transforaminal lumbar interbody fusion was an alternative to posterior lumbar interbody fusion for decompression surgeries. This study investigates the biomechanical responses of the unilateral and bilateral pedicle screw fixations with/without transforaminal lumbar interbody fusion cages under axial compression, flexion, and torsional loads. Ovine vertebrae were used in this study.

Cavernous hemangiomas of the third ventricle: Alternative surgical routes in two cases.
