Soviet psychiatric abuse: allegations met by red tape

Responding to accusations by human rights groups concerning the confinement of dissidents in mental hospitals, the Soviet All-Union Society of Psychiatrists (AUSP) has supplied the World Psychiatric Association (WPA) with data on two alleged cases of abuse and promised information on four more. Some member societies are suspicious that the move is simply a delaying tactic to forestall possible ouster of the AUSP from the WPA. Some members are also concerned that the WPA executive council's "overscrupulous" stance on confidentiality has hindered investigation of complaints of psychiatric abuse.     

Differential susceptibility of the axilla and groin of the mouse to chemical oncogenesis

INCIDENTAL to investigations of chemical oncogenesis, we have observed that 3-methylcholanthrene (3-MC)-induced subcutaneous sarcogenesis occurred more rapidly in the axillary than in the inguinal region of the mouse. Recently Auerbach et al. have described what may be a similar phenomenon-a marked tendency for tumour transplants to grow better cephalically(1,2).     

机翼载荷传递结构的质量估算

为了在机翼设计的初始阶段,给出比较准确的结构质量估算,在承载因子的基础上,结合变满应力理论与有限元技术,提出了一种采用承载因子系数进行质量估算的方法,并给出了其在桁条蒙皮式机翼结构中的应用方案.以5种外形相同但内部载荷传递结构不同的三角机翼为例,质量估算结果表明:在机翼设计的初始阶段,此方法不仅可以估算和比较不同承载结构方案的效率,同时也能预测出其相对更为准确的结构质量.     

The molecular neurobiology of depression

Unravelling the pathophysiology of depression is a unique challenge. Not only are depressive syndromes heterogeneous and their aetiologies diverse, but symptoms such as guilt and suicidality are impossible to reproduce in animal models. Nevertheless, other symptoms have been accurately modelled, and these, together with clinical data, are providing insight into the neurobiology of depression. Recent studies combining behavioural, molecular and electrophysiological techniques reveal that certain aspects of depression result from maladaptive stress-induced neuroplastic changes in specific neural circuits. They also show that understanding the mechanisms of resilience to stress offers a crucial new dimension for the development of fundamentally novel antidepressant treatments.
