Corpus callosum abnormalities in psychopathic antisocial individuals may reflect atypical neurodevelopmental processes involving an arrest of early axonal pruning or increased white matter myelination. These findings may help explain affective deficits and previous findings of abnormal interhemispheric transfer in psychopathic individuals.

For this study, we analyzed the relationship between intrusive academic advising and community college student success. Utilizing a qualitative, single-case study design, we conducted interviews with 12 students who participated in an intrusive advising program at a large, urban community college in Texas. Analysis of the interview data revealed the benefits, limitations, and contributions to success of intrusive advising. This study addresses a notable gap in the extant literature, as few researchers have published empirical examinations on the impact of intrusive academic advising within the community college context. The findings can be used to improve the delivery of academic advising and student support services at community colleges.

-Understanding reproductive development effects and transferable properties to next generation of zinc oxide nanoparticles is necessary for prevention of its potential risks. To accomplish this, rats were exposed to zinc oxide nanomaterials (500 mg/kg bw) of less than 100 nm beginning 2 weeks before mating to postnatal day 4. In addition, body distribution of zinc concentration was evaluated in dams and offspring. Rat treated with nano-zinc oxide showed reduced number of born/live pups, decreased body weights of pups and increased fetal resorption. Zinc oxide nanomaterials were also distributed to organs such as mammary tissue of dams and liver and kidney of pups. These results indicate that zinc oxide nanoparticles-exposure before and during pregnancy and lactation could pose health risks to pregnant women and their fetus.

After knee replacement surgery, the use of continuous local anesthetic infusions in femoral and sciatic peripheral nerve catheters is an effective analgesic option. Limited data are available concerning the safety of peripheral nerve infusions in patients receiving low molecular weight heparin thromboprophylaxis. We report three cases of bleeding at femoral and sciatic catheter sites in patients receiving a single daily dose of enoxaparin (40 mg). In all cases, some bleeding was noticed before catheter removal; in one case involving catheter removal 3 h after enoxaparin administration, massive thigh swelling occurred. Physical therapy and discharge from the hospital were delayed in two cases but no other complications were seen. More data are needed to determine if it is necessary to use the same guidelines for managing peripheral nerve infusion catheters in patients receiving enoxaparin as with epidurals and other types of central nerve catheter infusions.
