Microscopic subinguinal varicocelectomy has a recurrence of less than 1%, and varicocele recurrence is supposed to be an uncommon post-surgery adverse event. At present, no guidelines exist for the management of recurrent varicoceles after surgery. In this report, we present two cases of post-surgery recurrent varicocele of the testis. Case_1 : A 23-year-old male patient who had undergone microscopic subinguinal varicocelectomy for a grade 3 varicocele was referred to our hospital because of recurrent varicocele...

REVIEW
Susan M Andersen, Elizabeth Przybylinski
Close relationships afford us opportunities to create and maintain meaning systems as shared perceptions of ourselves and the world. Establishing a sense of mutual understanding allows for creating and maintaining lasting social bonds, and as such, is important in human relations. In a related vein, it has long been known that knowledge of significant others in one's life is stored in memory and evoked with new persons-in the social-cognitive process of 'transference'-imbuing new encounters with significance and leading to predictable cognitive, evaluative, motivational, and behavioral consequences, as well as shifts in the self and self-regulation, depending on the particular significant other evoked...

Lupeol and stigmasterol, major phytosterols in various herbal plants, possess anti-inflammatory activities and have been proposed as candidates for anti-cancer agents, but their molecular mechanisms are still unclear. Here, we investigated the effects of lupeol and stigmasterol on tumor and endothelial cells in vitro and their anti-cancer activities in vivo. Our results demonstrated that lupeol and stigmasterol suppressed cell viability, migration, and morphogenesis of human umbilical vein endothelial cells (HUVECs) but not cholangiocarcinoma (CCA) cells...

A 66-year-old man with poorly controlled type 2 diabetes was admitted for acute bilateral calf pain in the context of coronary artery disease, chronic renal failure, and peripheral neuropathy. Lower-extremity Doppler ultrasound excluded deep vein thrombosis. FDG-PET was performed to exclude a suspected infection because of elevated white blood cells and inflammatory markers but normal creatinine kinase levels. PET scan demonstrated intense bilateral calf muscle and left thigh muscle uptake, which in combination with the patient's history was consistent with diabetic myonecrosis, a rare end-stage complication of diabetes...

BACKGROUND: Arterial spin labeling (ASL) based-noncontrast-enhanced 4D MR angiography (NCE 4D MRA) shows potential in characterizing cerebrovascular hemodynamics in cerebrovascular disorders. Ultrahigh-field theoretically benefits ASL signal with increased inherent signal-to-noise ratio (SNR) and prolonged blood T1 , which may provide improved delineation of vasculature in 4D MRA. PURPOSE: To investigate the feasibility of NCE 4D MRA using 3D Cartesian trajectory and stack-of-stars (SOS) golden angle radial trajectory at 7T...

An extensive 35 × 20 cm sized full-thickness abdominal wall defect was created after resection of aggressive abdominal fibromatosis in a 19-year-old male patient. Immediate reconstruction was not possible due to prolonged operation time and resulting severe bowel edema. A silicone sheet with NPWT was applied over the exposed viscera. After 1 week, silicone sheet was substituted with a composite mesh. Then, abdominal wall reconstruction with bilateral free anterolateral thigh (ALT) flaps (30 × 12 cm and 25 × 12 cm sized) was performed...

Blood compatibility is a long sought-after goal in biomaterials research, but remains an elusive one, and in spite of extensive work in this area, there is still no definitive information on the relationship between material properties and blood responses such as coagulation and thrombus formation. Materials modified with heparin-mimicking polymers (HMP) have shown promise, and indeed may be seen as comparable to materials modified with heparin itself. In this work, heparin was conceptualized as consisting of two major structural elements: saccharide-containing and sulfonate-containing units, and polymers based on this concept were developed...

Liang Yu, Xifa Xu, Jian Liu, Xiaonong Fan
According to Qihai theory, academician SHI Xuemin established the acupuncture technique "controlling Qihai to regulate blood pressure" which focused on Renying (ST 9), and achieved favorable effects in clinical application. In this paper, based on the Qihai theory, from aspects of Yuanqi, Zongqi, Yingqi and Weiqi and relations among qi, blood and veins in TCM, and cardiac output, sympathetic nerve activity and blood vessels in modern medicine, the understanding on hypertension was explained. As a result, both TCM and modern medicine had consistency in the understanding of hypertension, reflecting the scientificity and practicability of this acupuncture technique...

BACKGROUND: Cutaneous venous malformation (VM) can be associated with internal vascular anomalies. Our objective was to investigate the frequency of internal vascular anomalies in patients with an isolated genital venous malformation to assess the utility of screening for internal findings. METHODS: We retrospectively reviewed our Vascular Anomalies Center database for patients with a focal genital venous malformation presenting between 1999 and 2016. Abdominal and pelvic imaging reports were reviewed for internal vascular anomalies...

Nephron sparing surgery (NSS) is increasingly utilized to treat patients with bilateral Wilms tumor. We present a case of NSS planning using a three-dimensional computerized and printed model of both kidneys with anatomical structures of interest (parenchyma, renal pelvis, major calyx, renal artery, renal vein, and tumor). This model allowed a better understanding of the anatomic relation between the tumor and the normal kidney on each side, improving the surgical planning and the preoperative discussion with the patient's family...

Dog bite injuries are common sources of morbidity with an estimated incidence of 4.5 million bites per year with over 350,000 requiring treatment in the emergency room. Children under the age of 14 are most likely to be affected with a peak age of 5-9 years old. We report a case of a 24-month-old female who sustained a large composite facial avulsion injury from a pit bull dog bite. The avulsed tissue involved a substantial portion of the patient's mid-face, including the entire soft tissue of the nose, upper lip, part of the left cheek, and left oral commissure...

Biomaterial vascularization remains a major focus in the field of tissue engineering. Biomaterial culture of endometrial cells is described as a platform to inform the design of proangiogenic biomaterials. The endometrium undergoes rapid growth and shedding of dense vascular networks during each menstrual cycle mediated via estradiol and progesterone in vivo. Cocultures of endometrial epithelial and stromal cells encapsulated within a methacrylamide-functionalized gelatin hydrogel are employed. It is reported that proangiogenic gene expression profiles and vascular endothelial growth factor production are hormone dependent in endometrial epithelial cells, but that hormone signals have no effect on human telomerase reverse transcriptase (hTERT)-immortalized endometrial stromal cells...

We report a rare case of cystic adventitial disease of popliteal artery with venous aneurysm of popliteal vein. A 46-year-old woman had sudden-onset intermittent claudication and coldness in her right leg. The right-sided ankle-brachial pressure index (ABI) was 1.01, but peripheral arterial pulsation was decreased at knee venting position. Computed tomography revealed simple cystic lesion of the popliteal artery and stenosis of the arterial lumen in this lesion. The patient was treated by complete resection of the cystic adventitial layer of popliteal artery...

Preclinical testing in rodent models is a ubiquitous part of modern biomedical research and commonly involves accessing the venous bloodstream for blood sampling and drug delivery. Manual tail vein cannulation is a time-consuming process and requires significant skill and training, particularly since improperly inserted needles can affect the experimental results and study outcomes. In this paper, we present a miniaturized, robotic medical device for automated, image-guided tail vein cannulations in rodent models...

High-pressure polymorphism of olivine (α-phase of Mg2SiO4) is of particular interest for geophysicists aiming to understand the structure and dynamics of the Earth's interior because of olivine's prominent abundance in the upper mantle. Therefore, natural and synthetic olivine polymorphs have been actively studied in the past half century. Here, we report a new high-pressure polymorph, the ε*-phase, which was discovered in a heavily shocked meteorite. It occurs as nanoscale lamellae and has a topotaxial relationship with the host ringwoodite (γ-phase of Mg2SiO4)...

Growing evidence suggests that increased intracranial pulsatility is associated with cerebral small vessel disease (SVD). We systematically reviewed papers that assessed intracranial pulsatility in subjects with SVD. We included 27 cross-sectional studies (n=3356): 20 used Doppler ultrasound and 7 used phase-contrast MRI. Most studies measured pulsatility in the internal carotid or middle cerebral arteries (ICA, MCA), whereas few assessed veins or cerebrospinal fluid (CSF). Methods to reduce bias and risk factor adjustment were poorly reported...
