09 mPa. At 10 mPa, both upregulation of osteogenic genes and higher alkaline phosphatase activity were observed. These results suggest that the intermittent shear of the order of 10 mPa can competently enhance osteogenic differentiation of rBMSCs compared to static culture.Observations and analyses of a microscopic object are essential processes in various fields such as chemical engineering and life science. Microfluidic techniques with various functions and extensions have often been used for such purposes to investigate the mechanical properties of microscopic objects such as biological cells. One of such extensions proposed in this context is a real-time visual feedback manipulation system, which is composed of a high-speed camera and a piezoelectric actuator with a single-line microfluidic channel. Although the on-chip manipulation system enables us to control the 1 degree-of-freedom position of a target object by the real-time pressure control, it has suffered from unintended changes in the object orientation, which is out of control in the previous system. selleck In this study, we propose and demonstrate a novel shear-flow-based mechanism for the control of the orientation of a target object in addition to the position control in a microchannel to overcome the problem of the unintended rotation. We designed a tributary channel using a three-dimensional hydrodynamic simulation with boundary conditions appropriate for the particle manipulation to apply shear stress to the target particle placed at the junction and succeeded in rotating the particle at an angular velocity of 0.2 rad/s even under the position control in the experiment. The proposed mechanism would be applied to feedback controls of a target object in a microchannel to be in a desired orientation and at a desired position, which could be a universally useful function for various microfluidic platforms.Loeys-Dietz syndrome (LDS) is a connective tissue disorder with associated systemic vasculopathies including intracranial arterial aneurysm formation and dissections. LDS is a relatively less well-known entity compared with other connective tissue disorders, such as Ehlers-Danlos or Marfan syndrome, and consequently experience in the management of the associated intracranial aneurysms is suboptimal. We present a case of surgical clipping of a middle cerebral artery aneurysm in a patient with LDS. A 46-year-old female with LDS (type III) was found to have a right middle cerebral artery (MCA) bifurcation aneurysm following vascular screening. The decision was made to surgically clip the aneurysm after consultation in our neurovascular multidisciplinary team meeting. A standard right pterional craniotomy was performed and the aneurysm was secured with 2 straight Sugita clips. The temporal M2 branch was noted to be thin walled and this prompted application of the second tandem clip, rather than risk re-positioning the initial clip. In our case, the MCA aneurysm neck was robust enough to take a clip without any complications, and therefore we suggest that the presence of LDS is not an absolute contra-indication to perform open craniotomy and clipping.Autologous flap reconstruction is widely used after skin sparing mastectomy to reconstruct the appearance of the breast. We present 2 cases of breast cancer recurrence in a deep inferior epigastric perforator reconstruction, including a 65-year-old female with history of papillary carcinoma and a 35-year-old female with history of a high grade invasive ductal carcinoma with extensive ductal carcinoma in situ. Differential imaging considerations of the post mastectomy patient are reviewed. Typical appearance of a deep inferior epigastric perforator flap reconstruction as well as location and timing of presentation may help differentiate a recurrence from the more commonly encountered postsurgical etiologies.Breast pseudoaneurysm is an extremely rare complication of interventional breast procedures. Pregnancy and lactation are associated with increased breast vascularization, which may act as a risk factor. We present the case of a 36-year-old woman in the third trimester of a spontaneous twin pregnancy, who presented with a newly-detected BI-RADS 4 mass in her right breast. The patient requested not to defer a biopsy until after the pregnancy, and an ultrasound-guided breast core biopsy was performed. The patient presented bleeding during the procedure, but no hematomas or other vascular lesions were immediately detected. During follow-up, a breast ultrasound revealed an anechoic circumscribed mass and high-velocity blood flow. The color Doppler showed a spiral blood flow with the Yin-Yang sign, together with a communication channel between the sac and feeding artery. A diagnosis of breast pseudoaneurysm was made. The patient was managed conservatively, and breastfeeding continued normally. This case report highlights the importance of color Doppler in the detection of pseudoaneurysms, and the need to consider deferring invasive breast procedures in pregnant women when possible.Background Early-onset Alzheimer's disease is a rare condition that differs from the usual memory-disordered presentation of typical Alzheimer's disease. Early-onset Alzheimer's disease is believed to have a genetic basis, and sporadic Alzheimer's disease has been associated with sortilin-related receptor 1 polymorphism. Case presentation This report describes and discusses the family report of a 59-year-old patient with early-onset Alzheimer's disease that may have been associated with a sortilin-related receptor 1 gene mutation. The patient was hospitalized in August 2008 for gradually progressive amnesia. Brain magnetic resonance imaging showed that the patient presented with whole-brain atrophy (especially in the bilateral medial temporal lobe and hippocampus). He had an initial Mini-Mental State Examination score of 15 (time orientation 4/5; place orientation 4/5; language immediate memory 2/3; attention and calculation 1/5; delayed memory 0/3; naming 1/2; language retelling, understanding, and expression 3/6; visuospatial ability 0/1). Whole-exome sequencing showed a sortilin-related receptor 1 gene mutation, c.3575G>A (chr11121448104), which was detected in the patient and his children. Discussion Patients with early-onset Alzheimer's disease present with obvious deficits in language, visuospatial abilities, praxis, or other nonmemory cognitive functions. In this case, the speech, memory, and visuospatial impairment of the patient may be associated with the sortilin-related receptor 1 gene mutation. Atrophy of the bilateral medial temporal lobe/hippocampus on magnetic resonance imaging may be an important marker of early-onset Alzheimer's disease. A sortilin-related receptor 1 gene mutation, c.3575G>A (chr11121448104), may increase the risk of Alzheimer's disease.
