Different species of Trichoderma especially T. harzianum (Th2 biotype in Europe and Th4 in America) considered as causal agent of green mould disease on button mushroom (Agaricus bisporus) casing beds. In this study, 100 fungal isolates were collected and purified from different mushroom growing units in Tehran province and Urmia (NW Iran). Totally, 60 isolates of T. harzianum, 27 isolates of T...

We examined the mycoparasitic and saprotrophic behavior of isolates representing groups of Trichoderma harzianum to establish a mechanism for the aggressiveness towards Agaricus bisporus in infested commercial compost. Mycoparasitic structures were infrequently observed in interaction zones on various media, including compost, with cryoscanning electron microscopy. T. harzianum grows prolifical...

The most common biological control agents (BCAs) of the genus Trichoderma have been reported to be strains of Trichoderma virens, T. harzianum, and T. viride. Since Trichoderma BCAs use different mechanisms of biocontrol, it is very important to explore the synergistic effects expressed by different genotypes for their practical use in agriculture. Characterization of 16 biocontrol strains, pre...

Laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant Lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. Factors evaluated were Lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 dS cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). The maximum germination in salinity stres...

Актуальність. Математичне моделювання корекції сколіотичних деформацій хребта дозволяє без хірургічного втручання провести аналіз ефективності різних методів лікування в декількох варіантах. При дослідженні тракційних способів застосовувалися переважно експериментальні методи досліджень. Мета: дослідити напружено-деформований стан моделей з різним ступенем сколіотичної деформації при задньому с...

BACKGROUND Cervical and high thoracic epidural anesthesia and analgesia have gained increasing importance in the treatment of painful conditions and as components of anesthetics for cardiac and breast surgery. In contrast to the hanging-drop technique, the loss-of-resistance technique is thought to rely on the penetration of the ligamentum flavum. However, the exact morphology of the ligamentum...

Low-cost biosorbents (ginkgo leaf, osmanthus leaf, banyan leaf, magnolia leaf, holly leaf, walnut shell, and grapefruit peel) were evaluated in the simultaneous removal of La3+, Ce3+, Pr3+, Nd3+, Sm3+, Eu3+, Gd3+, Yb3+, Lu3+, UO22+, Th4+, Y3+, Co2+, Zn2+, Ni2+, and Sr2+ from aqueous solutions. In single metal systems, all adsorbents exhibited good to excellent adsorption capacities toward lanth...

Chronically human immunodeficiency virus type 1 (HIV-1) strain IIIB-infected human TH4-7-5 astrocytoma cells show low-level virus production. Cocultivation of TH4-7-5 cells with myelomonocytic cells led to active virus production in these target cells after a lag period, indicating cell-determined restriction of virus replication in the glial cells. HIV-1 transcript patterns of TH4-7-5 cells co...
