Culture extends biology in that the setting of development shapes the traditions that individuals learn, and over time, traditions evolve as occasional variations are learned by others. In humans, interactions with others impact the development of cognitive processes, such as sustained attention, that shape how individuals learn as well as what they learn. Thus, learning itself is impacted by c...

Prolapsed epiploica of the sigmoid colon through the vaginal cuff is a rare finding that has never been reported after total laparoscopic hysterectomy. We encountered a case of prolapsed epiploica of the sigmoid colon in a 40-year-old female, 4 months status after total laparoscopic hysterectomy. Diagnostic laparoscopy demonstrated prolapsed epiploica of the sigmoid colon through a dehisced vag...

Humans can use hand tools smoothly and effectively in varying circumstances; in other words, skillfully. A few other species of primates crack encased foods using hammer tools and anvils. Are they skilled? Positioning the food on the anvil so that it does not fall off when struck is a component of skilled cracking. We discovered that bearded capuchin monkeys deliberately place palm nuts in a re...

We describe a procedure which may be helpful to any disorganized carpenter who has a mixed pile of bolts and nuts and wants to nd the corresponding pairs of bolts and nuts. The procedure uses our (and the carpenter's) ability to construct e ciently highly expanding graphs. The problem considered is given a collection of n bolts of distinct widths and n nuts such that there is a 1-1 corresponden...

The problem of matching nuts and bolts is the following Given a collection of n nuts of distinct sizes and n bolts such that there is a one to one correspondence between the nuts and the bolts nd for each nut its corresponding bolt We can only compare nuts to bolts That is we can neither compare nuts to nuts nor bolts to bolts This humble restriction on the comparisons appears to make this prob...

The effects of tree nuts on risk factors for coronary heart disease (CHD), in particular blood lipids, have been investigated in a number of studies and the beneficial effects are now recognized. The beneficial effects of nuts on CHD in cohort studies have also been clearly demonstrated. However, while there is also reason to believe the unique micro- and macronutrient profiles of nuts may help...

BACKGROUND Breast cancer can be diagnosed easily in most cases. However, occasionally, we are faced with some conditions that can mimic it. These may include inflammations, benign tumors, cysts, hematomas, or, more rarely, focal necrosis. CASE PRESENTATION This report presents a case of focal breast necrosis following myocardial revascularization with the left internal mammary artery, which i...

This article summarizes the main conclusions drawn from a conference on the health effects of nut consumption and identifies priority areas for future research. Individuals with higher intakes of nuts generally have higher intakes of many beneficial dietary constituents. More information is needed on nut composition, the bioavailability of nutrients, and other bioactive constituents. Better met...
