Abstract. In modern molecular systematics, matrices of unordered multistate characters, such as DNA sequence alignments, are used for analysis with no further re-coding procedures nor any a priori determination of character polarity. Here we present 1001, a simple freely available Python-based tool that helps re-code matrices of non-additive characters as different types of binary matrices. Des...

OBJECTIVE To describe contraceptive use and attitudes towards contraceptive use in Sweden which has the highest abortion rate in Western Europe. Secondary objectives were to investigate knowledge of contraceptive methods and outcomes of unplanned and unwanted pregnancies. DESIGN Telephone survey. SETTING National survey of women living in Sweden. POPULATION Women between 16 and 49 years. ...

HIV-1 integrase (IN) is essential for the integration of viral DNA into the host genome and an attractive therapeutic target for developing antiretroviral inhibitors. LEDGINs are a class of allosteric inhibitors targeting LEDGF/p75 binding site of HIV-1 IN. Yet, the detailed binding mode and allosteric inhibition mechanism of LEDGINs to HIV-1 IN is only partially understood, which hinders the s...

Suppressor of cytokine signaling (SOCS)-1 protein modulates signaling by IFN-gamma by binding to the autophosphorylation site of JAK2 and by targeting bound JAK2 to the proteosome for degradation. We have developed a small tyrosine kinase inhibitor peptide (Tkip) that is a SOCS-1 mimetic. Tkip is compared in this study with the kinase inhibitory region (KIR) of SOCS-1 for JAK2 recognition, inhi...

BACKGROUND Despite claims that the Millennium Development Goals (MDG) targets on access to safe drinking water have been met, many 100 s of millions of people still have no access. The challenge remains how to provide these people and especially young children with safe drinking water. METHOD We report a longitudinal study designed to assess the effectiveness of an intervention based on provi...

Human Papillomaviruses (HPVs) are small double-stranded DNA viruses that infect the cutaneous or mucosal epithelium. The high-risk genital HPVs are associated with squamous intraepithelial lesions of the anogenital region that can progress to cancer. Cervical cancer is the third leading cause of cancer death in women worldwide, yet there are no specific therapeutic treatments for HPV-associated...

Actinomycetes isolated from marine sediments along the southeast coast of Bay of Bengal were investigated for amylolytic activity. Marine actinomycete BTSS 1001 producing an alkaline amylase was identified from marine sediment of Diviseema coast, Bay of Bengal. The isolate produced alkaline amylase with maximum amylolytic activity at pH 9.5 at 50°C. The organism produced white to pale grey subs...
