Polysaccharide from the Roots of Polygonum Equisetiforme Sibth. & Sm.: Isolation, Chemical Composition, Antioxidant Potential and Cytotoxic Activity

A water-soluble polysaccharide (PEP) was isolated and purified from the aqueous extract of Polygonum equisetiforme Sibth. & Sm. roots. Structural features of PEP were investigated by a combination of instrumental and chemical analyses, including acid hydrolysis, methylation analysis, IR, GPC, HPLC and GC/MS. The results indicated that PEP has a backbone of (1→4)-linked glucose residues, which o...

Mendelian Inheritance of Chromosome Shape in Matthiola.

A variety of stock (Matthiola ilzcana R. Br.) known as Snowflake has been shown by FROST (1919) to produce frequent mutants of at least eight distinct kinds. These mutant forms are genetically inconstant, part of the progeny always being normals. These forms have been determined (FROST and MANN 1924, and papers in preparation) to be trisomic. Within, the variety Snowflake, all plants cytologic...

Characterizing sleep behavior of the wild black rhinoceros (Diceros bicornis bicornis).

STUDY OBJECTIVES The objectives of this study were to characterize sleep patterns and determine factors, including sex, age, season, and environmental pressures, that influence sleep in the endangered black rhinoceros (rhino; Diceros bicornis bicornis). DESIGN To noninvasively observe sleep behavior of wild rhinos, digital infrared cameras were erected on poles at two bedding sites from Septe...

Two Cases of Uterus Bicornis

Spontaneous Twin Pregnancy in Uterus Bicornis Unicollis

Abnormal fusion of the Müllerian ducts or failure of resorption of the septum causes varying degrees of congenital uterine malformation. They are often associated with reproductive problems such as miscarriage, premature labour, premature rupture of the membranes, or malpresentation. Twin gestation in a case of bicornuate uterus is extremely rare. A 37-year-old multiparous woman conceived a twi...
