The investigation of human placental nutrient transfer and hormonal secretion presents a particular challenge because these processes depend on the intactness and orientation of the unicellular epithelial sheet of villous syncytiotrophoblast that mediates them. The isolated perfused placental cotyledon retains the architecture of the villi and has been very useful, but the presence of the non-t...

BACKGROUND AND PURPOSE Left-sided strokes are reported to be more common than right-sided strokes, but it is unknown whether they occur more often or are simply recognized more easily by clinicians. In a large unselected community-dwelling population, we examined the frequency of clinical left- and right-sided strokes and transient ischemic attacks (TIAs) and compared it with the frequency of l...

Objective The purpose of this study was to investigate whether changes occurred in the clinical features of acute colonic diverticulitis (ACD) over a period of 10 years, to estimate the long-term probability of disease recurrence and to investigate whether it could be treated in an outpatient setting. Methods Between January 1998 and January 2009, 488 ACD patients were diagnosed and treated in ...

Abstract. The purpose of this paper is to prove strong type inequalities with one-sided weights for commutators (with symbol b ∈ BMO) of several one-sided operators, such as the one-sided discrete square function, the one-sided fractional operators, or one-sided maximal operators given by the convolution with a smooth function. We also prove that b ∈ BMO is a necessary condition for the bounded...

Colorectal cancer (CRC) can be characterized by the location of the primary tumor being within the colon [1]. Right-sided colon cancer (RCC) is derived from the embryologic midgut, including the proximal two-thirds of the transverse colon, ascending colon, and cecum. Left-sided colon cancer (LCC) is derived from the embryologic hindgut, which includes the distal third of the transverse colon, s...

in a cross-sectional study aiming to investigate the anatomical distribution of colorectal cancer in a six years period, patients file were studied and 150 patients with colorectal cancer were selected based on age, gender, place of residency, place of anatomical tumor and biological symptom. the findings indicated that 91(59.9) of patients had adenocarcinum, 54 (35.5) pulyp and 7 (4.6) had oth...

the development of ascites in hyperthyroid patients is a rare phenomenon and usually occurs in the context of exaggeration of right-sided heart failure , so it is categorized as high saag ascites. in this case report, we present a 73-year-old man who was referred to us with anorexia, severe weight loss, anemia, lower limbs pitting edema, and also exudative, low saag ascites. extensive work up r...

right-sided heart thrombus is a life-threatening condition that necessitates immediate therapy. detection of right-sided heart thrombus is usually via transthoracic echocardiography. generally, thrombolysis is considered a treatment of choice, but there is currently no consensus about the optimal therapeutic choice. we present a case of multiple right atrial thrombi with concurrent mobile and b...

The school choice problem is formulated as a one-sided or a twosided matching problem. However, neither model adequately captures the features of the market design applications of school choice. In particular, the one-sided matching solution may be politically infeasible; and the two-sided matching solution may involve ineffi ciencies. We introduce a generalized model that encompasses one-sided...
