In 94% brain specimens had a recurrent artery of Heubner while in 6% of the brains we could not identify the artery. The artery was present as a single vessel in 76% of cases, and as a double vessel in 24% of cases. It originated from the junction of the anterior cerebral artery and the anterior communicating artery in 60% of the specimens, from the A2 segment of the anterior cerebral artery in 21% of the specimens, and from the A1 segment of the anterior cerebral artery in 19%. The length of the recurrent artery of Heubner ranged from 14 to 46 mm, with a mean value of 24 mm. The diameter of the artery ranged from 0.9 to 2.8 mm, with a mean value of 1.3 mm. ...
The anterior ulnar recurrent artery is an artery in the forearm. It is one of two recurrent arteries that arises from the ulnar artery, the other being the posterior ulnar recurrent artery. It arises from the ulnar artery immediately below the elbow-joint, runs upward between the brachialis and pronator teres muscle and supplies twigs to those muscles. In front of the medial epicondyle it anastomoses with the superior and Inferior ulnar collateral arteries.

RESULTS: A total of 24 RAHs were recognised in 20 patients: 7 arose from the A1, 5 from the anterior cerebral artery (ACA)-anterior communicating artery (Acom), 11 from the A2, whereas in 1 case, the segment of origin from the ACA could not be identified. Seventeen arteries arose from the lateral wall of the ACA and seven from the superior wall of the A1 segment of the ACA. The RAH was bilaterally seen in 3 patients and unilaterally in 17 with one double RAH. Five RAHs were visible only after contrast injection in the contralateral internal carotid artery. A horizontal segment was visible in 7 arteries, a horizontal followed by a vertical segment without visible intraparenchymal branching pattern was seen in 6 and a horizontal and vertical segment with visible intraparenchymal branching pattern was seen in 11. In five, the artery made a half loop with an inferior-convex curve just before the vertical segment, and in two cases, a full loop was observed ...
The radial recurrent artery arises from the radial artery immediately below the elbow. It ascends between the branches of the radial nerve, lying on the supinator muscle and then between the brachioradialis muscle and the brachialis muscle, supplying these muscles and the elbow-joint, and anastomosing with the terminal part of the profunda brachii. ...
A2 anterior cerebral artery aneurysm Also named Proximal pericallosal artery aneurysm. The A2 aneurysms are located between the anterior communicating artery complex and the genu of the corpus callosum on the frontobasal branches. Epidemiology They are very rare with an incidence of 0.2-1% of all intracranial aneurysms . In the
Hi, One week ago, after an MRI and then an MRA, two small aneurysms were discovered on my Anterior Communicating Artery, one leaning anteriorly and the other posteriorly. The MRA states that all of the blood flow is running through the A2 segment of the Anterior Cerebral Artery, since I am missing the A1 segment of the Anterior Cerebral Artery and the A2 segment looks fenestrated as well. In addition, the MRA could not rule out MS or other demylinating diseases, which was the initial

The formation of an area of NECROSIS in the CEREBRUM caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction ...
Researchers monitored the volunteers blood flow through their brains with an ultrasound. They found that increased blood flow through the anterior cerebral artery, located in the middle of the brain behind the eyes, caused it to swell up suddenly as the temperature dropped. This causes the pain we know as brain freeze.. The scientists described this act as a defensive mechanism for the brain. Since the temperature drops and the brain requires warmth to work, this widening of the artery provides a way to move the coldness along quicker and return the artery to its normal temperature. So the next time you get a blindly headache after downing a milkshake, know thats just your brains way of protecting itself. ...
Various movement disorders associated with cerebral infarction have been introduced. However patients with anterior cerebral artery territory infarction presenting with hemichoreoballism have never been reported. We present a 64-year-old man with hemichoreoballism and frontal alien hand syndrome on his right hand. Diffusion weighted brain MRI revealed hyperintensities in anterior two third of corpus callosum and superior frontal gyrus. Hemichoreoballism was improved after one day treated by clonazepam. We report the case with hemichoreoballism after anterior cerebral artery territory infarction. ...
Ischemic lesions within the territory of the anterior cerebral artery present with a variety of clinical signs and symptoms. Among these, frontal alien hand syndrome is rare and easily overlooked in the acute clinical setting, but significantly impacts on functional activities of daily life. Given its rareness, very little is known about its long-term outcome. To shade some more light onto this issue, clinical presentation, course of rehabilitation and outcome of two illustrative cases of frontal alien hand syndrome following anterior cerebral artery stroke are presented. Within seven and nine months from symptom onset, respectively, the clinical symptoms of frontal alien hand had resolved completely in both cases. We conclude that frontal alien hand syndrome has a favourable long-term outcome.

Fig 2. Classification of the anatomic variations in the circle of Willis. In the "textbook" type, both the precommunicating segment of the anterior cerebral artery (A1) and that of the posterior cerebral artery (P1) were normal in size. The next group included both right and left A1 hypoplasia. Because no significant difference between cerebral arteries on the right and left sides has been established,5,18 we combined right and left A1 hypoplasia into A1 hypoplasia. The next group included right and left P1 hypoplasia, which again were treated as a single category, P1 hypoplasia. "Other" type included a combination of A1 hypoplasia and P1 hypoplasia, bilateral P1 hypoplasia, as well as other unclassified variations.

Results 23 cerebral aneurysms in 22 patients were treated with the Pipeline device at our institution during our studys time period. 18 patients were female (81.8%) and four male (18.2%), with a mean age of 59.5 years (median 63 years, range 31-81 years). 22 aneurysms were unruptured (95.3%) and one was ruptured (4.3%). Aneurysm locations were: seven in the internal carotid artery (ICA) below the ophthalmic artery (30.4%), six in the periophthalmic ICA (26.1%), five in the supraclinoid ICA (21.7%), two in the middle cerebral artery (8.7%), one in the anterior cerebral artery (4.3%), one in the vertebral artery (4.3%), and one in the basilar artery (4.3%). Mean maximum aneurysm sac dimension was 11.4 mm (median 10 mm, range 2.1-27 mm) and mean aneurysm neck size was 5.6 mm (median 4.8 mm, range 1.4-17 mm). Mean number of Pipeline devices deployed was 1.3 (median 1, range 1-5). Dyna-CTA was performed in 15 cases (65.2%) and balloon angioplasty of the Pipeline construct to achieve adequate wall ...
From February 2002 to October 2003, we performed MRA of coiled intracranial aneurysms for long-term follow-up or as a baseline for follow-up after coil placement in patients who gave informed consent. MRA as a baseline was scheduled in an early period after coil placement and in a period around follow-up DSA in the chronic phase. Seventy patients with 70 coiled aneurysms uneventfully and successfully underwent 98 MRA studies. Included in this study were MRA images obtained within 3 days after coil placement (early phase, n = 24), and MRA within 7 days of follow-up DSA 5-41 (9 ± 7) months after coil placement (chronic phase, n = 27). Consequently, 51 MRA studies of 39 coiled aneurysms (two ruptured) of 39 patients were compared with the corresponding DSA studies. The mean age ± SD of the patients was 59 years ± 9; nine patients were male. Aneurysms were located in internal carotid artery (n = 27), anterior cerebral artery (n = 1), basilar artery (n = 10), and vertebral artery (n = 1). Maximum ...
The patients with subarachnoid haemorrhage in this study were selected because they showed secondary cererebral hypoxia/ischaemia of varying severity. Thus case 1 had a long lasting episode of secondary ischaemia leading to cerebral infarction in the microdialyisis probe area, cases 2 and 3 temporary secondary hypoxia/ischaemia without infarction in the probe area, and case 4 minor disturbances of energy metabolism and no structural changes in the frontal lobe harbouring the microdialyisis probe.The ischaemic event in case 1 was associated with a pronounced increase of D-glycerol. This probably reflected profound ischaemia with energy failure as the D-L/P ratio rise was large and accompanied by an undetectable D-glucose concentration and increased D-hypoxanthine and D-glutamate.15 This was supported by the occlusion of the right anterior cerebral artery diagnosed by a second angiography and the infarct development in the microdialyisis probe area according to CT and PET.15 In view of these ...

To elucidate the role of the internal elastic lamina in the development of cerebral aneurysm, the bifurcation of the anterior cerebral artery and olfactory artery was histologically studied in control and experimental rats treated with unilateral carotid ligation and renal hypertension. Various stages of aneurysm formation were compared, and it was found that early aneurysmal changes were always present just distal to the apical intimal pad on the anterior cerebral artery side. The internal elastic lamina was thinned and fragmented just distal to the pad even in the very early stage of aneurysm formation when the medial layer was still present. In control rats, the internal elastic lamina had a tendency to thin and fragment at the site where aneurysms would develop in experimental rats. Our study shows that changes of the internal elastic lamina were present just distal to the pad even in control rats, which never develop cerebral aneurysms. Under hemodynamic stress augmented by experimental ...
BACKGROUND The aim of the present study was to evaluate the technical viability of the unilateral pterional approach to simultaneously treat symmetrical bilateral aneurysm (mirror image) of the middle cerebral arteries (SBAMCA) and to determine the morbidity and mortality rates of this approach. METHODS Forty-six patients with SBAMCA underwent unilateral pterional craniotomy within a period of 9 years. Most patients were women (24, 80.0%) and mean age was 40.7 years. RESULTS Obliteration of the contralateral aneurysm was not possible in 16 patients (34.8%) because of brain edema in 8 patients operated on during the acute phase, lateral projection of the aneurysm in 3, a very long contralateral M1 segment in 4, and the presence of atheromatous plaques at the MCA bifurcation and aneurysm neck in 1. The remaining 30 patients (65.2%) were submitted to the proposed treatment. Final evaluation showed that 26 patients (86.7%) were Glasgow Outcome Scale (GOS) V, 1 patient (3.3%) was GOS IV, 2 patients (6.6%

Variations of the Circle of Willis at the End of the Human Embryonic Period[4] "Variations of the circle of Willis (CW) influence blood supply to the brain and adjacent structures in adults. We examined the formation of the CW in 20 human embryo samples at the end of the embryonic period using 3-D reconstructions of serial histological sections. The CW was closed in all samples, and did not form in a single plane, but was composed of multiple stair-like planes. The artery acutely curved at the caudal part of the CW, namely, at the inlet of the basilar artery and bifurcation of the P1 segment of the posterior cerebral artery (PCA), reflecting flexure of the mesencephalon and diencephalon at this stage. Variations were observed in 17 of 20 samples-only anterior parts (anterior communicating artery [Acom] and anterior cerebral artery [ACA]) in 10 samples, only posterior parts (posterior communicating artery [Pcom]) in one sample, and both anterior and posterior parts in six samples. Variations ...

A patient developed weakness of the right leg and homolateral ataxia of the arm, caused by a subcortical infarct in the area supplied by the anterior cerebral artery in the left paracentral region, demonstrated by CT and MRI. Cerebral blood flow studied by technetium-labelled hexamethyl-propylene-amine oxime using single photon emission computed tomography showed decreased blood flow in the left lateral frontal cortex and in the right cerebellar hemisphere ("crossed cerebral-cerebellar diaschisis"). The homolateral ataxia of the arm may be caused by decreased function of the right cerebellar hemisphere, because of a lesion of the corticopontine-cerebellar tracts, whereas crural hemiparesis is caused by a lesion of the upper part of the corona radiata.. ...

Watershed infarcts involve the junction of the distal fields of 2 nonanastomosing arterial systems. Classic neuropathologic studies1 describe 2 distinct supratentorial WS areas: (1) between the cortical territories of the anterior cerebral artery (ACA), middle cerebral artery (MCA), and posterior cerebral artery (PCA); and (2) in the white matter along and slightly above the lateral ventricle, between the deep and the superficial arterial systems of the MCA, or between the superficial systems of the MCA and ACA. The former, superficial areas have been commonly referred to as the cortical watershed (CWS), and the latter have been referred to as the internal watershed (IWS).. In autopsy studies, CWS and IWS infarcts-also termed external and internal border-zone infarcts, respectively-together represent ≈10% of all brain infarcts.2 However, because WS infarction is seldom fatal, this is probably an underestimate, and imaging studies in severe internal carotid artery (ICA) disease report an ...
BACKGROUND AND PURPOSE: Current knowledge of the collateral circulation remains sparse, and a noninvasive method to better characterize the role of collaterals is desirable. The aim of our study was to investigate the presence and distal flow of collaterals by using a new MR perfusion territory imaging, vessel-encoded arterial spin-labeling (VE-ASL). MATERIALS AND METHODS: Fifty-six patients with internal carotid artery (ICA) or middle cerebral artery (MCA) stenosis were identified by sonography, VE-ASL was performed to assess the presence and function of collateral flow. The perfusion information was combined with VE maps into high signal-intensity-to-noise-ratio 3-colored maps of the left carotid, right carotid, and posterior circulation territories. The presence of the anterior and posterior collateral flow was demonstrated by the color of the standard anterior cerebral artery/MCA flow territory. The distal function of collateral flow was categorized as adequate (cerebral blood flow [CBF] >= ...

The theory of oncogenes was foreshadowed by the German biologist Theodor Boveri in his 1914 book Zur Frage der Entstehung Maligner Tumoren (The Origin of Malignant Tumours), Gustav Fisher, Jena, 1914. Oncogenes (Teilungsfoerdernde Chromosomen) that become amplified (im permanenten Übergewicht) during tumour development. Later on the term "oncogene" was rediscovered in 1969 by National Cancer Institute scientists George Todaro and Robert Heubner.[7]. The first confirmed oncogene was discovered in 1970 and was termed sarcom. Sarcoma was in fact first discovered as an oncogene in a chicken retrovirus. Experiments performed by Dr. G. Steve Martin of the University of California, Berkeley demonstrated that the sarcoma was indeed the oncogene of the virus.[8] The first nucleotide sequence of v-sarcoma was sequenced in 1980 by A.P.

APOBEC proteins have evolved in mice and humans as potent innate defences against retroviral infections. APOBEC3G (hA3G) in humans and mouse APOBEC3 (mA3) deaminate cytidine in single-stranded DNA which ultimately results in hypermutation of newly synthesized proviral DNA. Other deaminase-independent mechanisms of inhibition have been identified, such as directly inhibiting reverse transcription. Both HIV and murine leukemia viruses (MuLVs) have evolved mechanisms to evade the action of the APOBEC proteins. HIV encodes the Vif protein which binds to hA3G and facilitates its rapid degradation through the proteasome. The mechanism(s) by which exogenous MuLVs evade mA3 inhibitory activity is unknown. Exogenous MuLVs encode a glycosylated gag protein (gGag) originating from an alternate CUG start site upstream of the AUG start site of the Gag structural polyproteins. gGag is synthesized to similar amounts as the structural Gag polyprotein in MuLV infected cells but is glycosylated in the endoplasmic
