The aim of this study was to develop and demonstrate the potential of protein-based laser induced breakdown spectroscopy (LIBS) method to be used for the identification of beef, chicken, and pork in fermented sausage and salami products. In this respect, bulk protein and protein fractions rich in sarcoplasmic and myofibrillar protein of sausage and salami products were obtained and subjected to LIBS analysis.

Inter-vendor performance of deep learning in segmenting acute ischemic lesions on diffusion-weighted imaging: a multicenter study.

There is little evidence on the applicability of deep learning (DL) in the segmentation of acute ischemic lesions on diffusion-weighted imaging (DWI) between magnetic resonance imaging (MRI) scanners of different manufacturers. We retrospectively included DWI data of patients with acute ischemic lesions from six centers. Dataset A (n = 2986) and B (n = 3951) included data from Siemens and GE MRI scanners, respectively.

Challenges in Using the Posterior Inferior Cerebellar Artery for Revascularization of the Anterior Inferior Cerebellar Artery: A Microsurgical Anatomic Study.

Background: A bypass is usually required to prevent ischemia during the treatment of anterior inferior cerebellar artery (AICA) aneurysms. The intracranial (IC)-to-IC bypass provides several advantages over the extracranial-to-IC bypass in the posterior fossa. However, there are only 2 case reports about AICA revascularization with the posterior inferior cerebellar artery (PICA).

Points to consider when evaluating three-dimensional digital subtraction angiography of intracranial aneurysms and their effects on treatment.

Methods: Thirty-one consecutive patients scheduled for carotid stenting with severe internal carotid artery stenosis (>60%; the study group) and 30 control subjects were included. Ophthalmic artery (OA) Doppler sonography was performed in the control group and study group before and after stenting.

Sensitivity to acute cerebral ischemic injury in migraineurs: A retrospective case-control study.

Objective: Migraine, particularly with aura, is a risk factor for ischemic stroke. Recent data in migraine mutant mice suggest that cerebral hyperexcitability associated with migraine accelerates recruitment of ischemic penumbra into the core, resulting in faster infarct growth compared with wild type. We hypothesized that individuals with a history of migraine are more likely to exhibit increased recruitment of ischemic tissue into the infarct in acute stroke.

Material And Methods: Forty-nine patients with SCA aneurysms underwent endovascular treatment (25 female, 24 male; mean age 46.

Lumbar disc herniation in a patient with congenital vertebral body anomaly: a case report.

Lumbar disc herniation is characterized with low back and leg pain resulting from the degenerated lumbar disc compressing the spinal nerve root. The etiology of degenerative spine is related to age, smoking, microtrauma, obesity, disorders of familial collagen structure, occupational and sports-related physical activity. However, disc herniations induced by congenital lumbar vertebral anomalies are rarely seen.

Giant isolated mesenteric hydatid cyst case report without organ involvement.

A 21-year-old man presented with a 1-year history of intermittent attacks of abdominal distention and abdominal pain. Abdominal ultrasonography (USG) and abdominal computed tomography (CT) showed a large multicystic mass. After the operation, histopathological findings revealed a lamellated ectocyst and germinal layer with a thick outer, non-cellular membrane in the wall of the cyst, making a diagnosis of primary hydatid cyst for sure.

Do not forget the contralateral side: late onset bilateral carotid dissecting aneurysms.

Internal carotid artery dissection may occur spontaneously or following a blunt or penetrating trauma to the head and/or neck. Bilateral dissections and pseudoaneurysm formations are extremely rare and usually detected simultaneously. In this report, we present a trauma case with bilateral dissecting pseudoaneurysms of the carotid arteries; in whom, the one side was initially occult and then developed during the follow-up of the contralateral side.
