We have investigated the effectiveness and safety of a newly developed biological adhesive for repair of meniscal tear. The adhesive was composed of disuccinimidyl tartrate (DST) as a crosslinker and human serum albumin (HSA) as a hardener. To determine adequate concentration, bonding strength was measured using a tensiometer 5 min after applying the adhesive on the avascular zone tear of porci...

Tolerance to a vascularized allograft can be induced in adult animals by pregraft donor-specific blood transfusion (DST). Mechanisms underlying this effect appear to depend on unresponsiveness of alloreactive T-helper cells. In this study, we examined the roles of DST and cellular components of the allograft that are important in inducing T-cell unresponsiveness in a rat model. DST alone did no...

The Peruvian National Tuberculosis Control Program issued guidelines in 2006 specifying criteria for culture and drug-susceptibility testing (DST), including district-level rapid DST. All patients referred for culture and DST in 2 districts of Lima, Peru, during January 2005-November 2008 were monitored prospectively. Of 1,846 patients, 1,241 (67.2%) had complete DST results for isoniazid and r...

The Dexamethasone Suppression Test (DST) has been evaluated as a biological marker in psychiatry especially in depressive illness. A study on the DST involving 20 patients in Tan Tock Seng Hospital, Singapore, who fulfilled the Research Diagnostic Criteria for major depressive disorder and with 21 healthy controls was carried out. Two out of the 20 patients had abnormal DST responses.

In the directed Steiner tree (DST) problem, we are given an $n$-vertex edge-weighted graph, a root $r$, and collection of $k$ terminal nodes. Our goal is to find minimum-cost subgraph that contains path from $r$ every terminal. We present $O(\log^2 k/\log\log{k})$-approximation algorithm for DST runs in quasi-polynomial time, i.e., time $n^{{poly}\log (k)}$. By assuming projection game conjectu...

In 34 patients of endogenous depression and 30 normal controls, the dexamethasone suppression test (DST) had a sensitivity of 67.6%, a specificity of 93.3% and a positive predictive power of 92%, which compares favourably with other diagnostic tests in clinical medicine. DST non-suppressors were significantly more depressed as compared to DST suppressors, had a higher incidence of suicidal atte...

Acute caffeine administration increases cortisol and converts the dexamethasone suppression test (DST) to nonsuppression in normal humans; data concerning chronic administration as well as effects in depressed patients are minimal. To determine whether caffeine intake influenced DST results in depression, we retrospectively studied the relationship between regular daily caffeine consumption and...

The strong correlation between magnetic storms and southward interplanetary magnetic eld (IMF) is well known from linear prediction lter studies using the Dst and IMF data. However, the linear lters change signiicantly from one storm to another and thus are limited in their predicting ability. Previous studies have indicated nonlinearity in the magneto-spheric response as the ring current decay...

Natural disasters, including drought and salt stress, seriously threaten food security. In previous work we cloned a key zinc finger transcription factor gene, Drought and Salt Tolerance (DST), a negative regulator of drought and salt tolerance that controls stomatal aperture in rice. However, the exact mechanism by which DST regulates the expression of target genes remains unknown. In the pres...
