BACKGROUND Middle colic artery (MCA) aneurysms are very rare and exclusively reported with symptoms or rupture. We report successful laparoscopic elective surgery for both cecal cancer and MCA aneurysm in an 87-year-old man who presented with bloody stools. METHODS Diagnostic colonoscopy revealed a cecal tumor 40 mm in diameter that was histologically confirmed as a well-differentiated adenoc...

Cabri is characterized by an attractive advantage and provides wide-ranging benefits in the teaching of mathematics. Although today there have been many studies on edges Cabri, experiments Cabri-Express not widely explored. For this reason, a quasi-experimental study with randomized posttest only design involving 80 grade VII junior high school students Ruteng, Indonesia, was conducted to analy...

The middle cerebral artery (MCA) covers a large part of the cerebral hemispheres and is therefore exposed during surgical intervention in this area. Aspects of cerebral branches tend to vary, different branching patterns can be described, and several anomalies can be observed. Knowledge of these variations and anomalies is important and can be helpful to neurosurgeons and clinicians. The aim of...

BACKGROUND We performed this study to semi-quantitatively characterize the formation of leptomeningeal collaterals in acute middle cerebral artery (MCA) occlusion caused by intravascular balloon inflation. METHODS The anatomic extent of leptomeningeal collateral blood flow from the anterior cerebral artery territory to the MCA territory during occlusion of the M1 segment was graded based on a...

Primary mucinous cystadenocarcinoma (MCA) of the breast is a rare but pathologically distinct breast tumor. There have been some case reports on primary MCA of the breast; however, they have all focused on pathologic findings. Here, we report the radiologic findings of two cases of MCA along with a review of the literature. Breast MCA shows a circumscribed mass with some calcifications on mammo...

Sensitized T lymphocytes can mediate potent antitumor effects when transferred to tumor-bearing animals. Employing the MCA 105 and MCA 106 sarcomas, we were able to generate antitumor effector cells by immunization of syngeneic mice with tumor cells admixed with Corynebacterium parvum. These immune splenocytes could be further sensitized and expanded in culture by the in vitro sensitization (IV...

Herein we designed, synthesized, tested, and validated fluorogenic methylcoumarinamide (MCA) and chloromethylketone-peptides spanning the Lassa virus GPC cleavage site as substrates and inhibitors for the proprotein convertase SKI-1/S1P. The 7-mer MCA (YISRRLL-MCA) and 8-mer MCA (IYISRRLL-MCA) are very efficiently cleaved with respect to both the 6-mer MCA (ISRRLL-MCA) and point mutated fluorog...

Background: Large middle cerebral artery (MCA) infarcts may be complicated by and life-threatening brain edema. Objective: To identify brain computed tomographic (CT) findings that can predict neurologic deterioration in patients with large middle cerebral artery (MCA) territory infarctions. Neurological deterioration was defined as progressive drowsiness or signs of brain herniation. Patients ...

OBJECTIVE This study was aimed to evaluate relationship between hyperintense vessels (HV) on fluid-attenuated inversion recovery (FLAIR) and artery steno-occlusion related intracerebral collaterals. MATERIALS AND METHODS A total of 233 patients with 260 atherosclerotic lesions in the M1 segment of the middle cerebral artery (MCA) were examined with FLAIR and digital subtraction angiography (D...

The diving response is initiated by apnea and facial immersion in cold water and includes, besides bradycardia, peripheral vasoconstriction, while cerebral perfusion may be enhanced. This study evaluated whether facial immersion in 10 degrees C water has an independent influence on cerebral perfusion evaluated as the middle cerebral artery mean flow velocity (MCA V(mean)) during exercise in nin...
