Intensive training programme improves handwriting in a community cohort of people with Parkinson's disease.

Background: People with Parkinson's disease (PwP) often report problems with their handwriting before they receive a formal diagnosis. Many PwP suffer from deteriorating handwriting throughout their illness, which has detrimental effects on many aspects of their quality of life.

Aims: To assess a 6-week online training programme aimed at improving handwriting of PwP.

Toward a Regional Phosphorus (Re)cycle in the US Midwest.

Redirecting anthropogenic waste phosphorus (P) flows from receiving water bodies to high P demand agricultural fields requires a resource management approach that integrates biogeochemistry, agronomy, engineering, and economics. In the US Midwest, agricultural reuse of P recovered from spatially colocated waste streams stands to reduce point-source P discharges, meet agricultural P needs, and-depending on the speciation of recovered P-mitigate P losses from agriculture. However, the speciation of P recovered from waste streams via its chemical transformation-referred to here as recovered P (rP) differs markedly based on waste stream composition and recovery method, which can further interact with soil and crop characteristics of agricultural sinks.

Arterial Tortuosity Syndrome reveals function of dehydroascorbic acid in collagen and elastin synthesis: Implications for skin care.

Some investigations in Arterial Tortuosity Syndrome (ATS) suggest that impaired intracellular transport of the oxidized form of vitamin C (dehydroascorbic acid, DHAA) is at the core of the pathogenesis. Lack of vitamin C for lysyl- and prolyl-hydroxylase activity may explain the defects in collagen and elastin formation found in ATS, and draws strong parallels between ATS and scurvy. Topically applied vitamin C has a well-established basis in the field of skin care, and part of its benefit is attributed to proper collagen formation in the skin.

Extracellular signal-regulated kinase 7, a regulator of hormone-dependent estrogen receptor destruction.

Estrogen receptor alpha (ER alpha) degradation is regulated by ubiquitination, but the signaling pathways that modulate ER alpha turnover are unknown. We found that extracellular signal-regulated kinase 7 (ERK7) preferentially enhances the destruction of ER alpha but not the related androgen receptor. Loss of ERK7 was correlated with breast cancer progression, and all ER alpha-positive breast tumors had decreased ERK7 expression compared to that found in normal breast tissue.

Case report: treatment of an intracranial arteriovenous malformation in a patient with complicated hemophilia.

The authors describe a young man with hemophilia complicated by chronic hepatic dysfunction, hypodysfibrinogenemia, and immune thrombocytopenia that resulted in a complex coagulopathy. The patient had a ruptured occipital arteriovenous malformation. The malformation was managed by temporary correction of the coagulopathy using cryoprecipitate, platelet transfusions, and plasmapheresis with fresh frozen plasma replacement.

EFFECTS OF DROUGHT STRESS ON GROWTH RESPONSE IN CORN, SUDAN GRASS, AND BIG BLUESTEM TO GLOMUS ETUNICATUM.

The responses of mycorrhizal corn (Zea mays L.), sudan grass [Sorghum vulgare (Piper) Hitch.], and big bluestem (Andropogon gerardii Vitman) under drought stress were compared.

A comparison of currently used serum lipase and amylase procedures in the serial detection of enzyme elevations in acute pancreatitis.

Twenty-eight patients having acute pancreatitis were followed during convalescence with serum amylase and lipase determinations. Starch and p-nitrophenyl-oligosaccharide substrates were used for amylase. Dimercaptotributyrate and triolein were employed for lipase.
