Second chromosome inversion and genotypic frequencies at seven allozyme loci, differentially associated with inversions, were determined in seven natural populations of Drosophila buzzatii. The patterns of variation of allozymes and the inversion polymorphisms were significantly different, indicating the role of adaptive differentiation for the latter. Moreover, the patterns of population structure varied among allozyme loci, suggesting the operation of diversifying selection for certain loci. Differentiation was negligible for Leucyl‐amino peptidase (Lap) and Peptidase‐2 (Pep‐2), low to moderate for Aldehyde oxidase (Aldox), Peptidase‐1 (Pep‐1) and Esterase‐1 (Est‐1) and high for Esterase‐2 (Est‐2) and Xanthine dehydrogenase (Xdh). Significant linkage disequilibria were detected between inversions and Aldox, Est‐1, Est‐2 and Xdh. Multiple regression analyses of inversion and allele frequencies on environmental variables revealed the existence of clines for inversions, Est‐1, Est‐2, Xdh and Aldox along altitudinal, latitudinal and/or climatic gradients. Tests using conditional allele frequencies showed that Est‐1 and Aldox clines could be accounted for by hitchhiking with inversions, whereas natural selection should be invoked to explain the clines observed for Est‐2 and Xdh.

Background. Occupational therapy groups have been carried out as interventions in mental health settings across a variety of populations. Limited research explores the lived experience of individuals with depression following participation in recovery oriented occupational therapy groups. Purpose. To better understand how recovery oriented occupational therapy groups shape participants’ personal experience of daily life, including recovery. Method. Five individuals who had previously completed at least one recovery oriented occupational therapy group each participated in two in-depth semi-structured interviews. Analyses of the transcripts were completed using interpretative phenomenological analysis (IPA). Findings. Participants’ experiences of the recovery oriented occupational therapy groups ranged from positive to negative, with variable impacts on their lived experiences. Two major themes emerged: (a) participants’ perception of “normal” and (b) navigation of meaningful participation. Implications. Increased understanding of what aspects of recovery oriented occupational therapy groups are meaningful to individuals with depression can help support their personal recovery process.

Background and Purpose: We present the first case of combined arterial (vertebral artery dissection) and venous [central sinus vein thrombosis (CSVT)] diseases presenting as Opalski syndrome in a female patient following induced delivery. Case Description: A 32-year-old woman was admitted to our institute two weeks after induced delivery with intriguing neurological findings that were finally diagnosed as a combined venous-arterial disease. Although she was referred diagnosed with CSVT, her neurological findings indicated Wallenberg ‘plus’ syndrome with ipsilateral hemiparesis (Opalski syndrome), further confirmed by neuroimaging revealing arterial disease (vertebral artery dissection) combined with incidental acute CSVT. Coagulation, gynecological and cardiac problems were ruled out. Treatment consisted of continuous heparin with rigorous control of her blood pressure. Nine days later, the patient was discharged with prominent improvements. Most of the symptoms resolved following 3 months of rehabilitation. Conclusions: Atypical strokes (such as Opalski syndrome) might present in postpartum patients. This rare diagnosis should be suspected in patients with Wallenberg ‘plus’ syndrome, and neuroimaging studies for determining the presence of arterial disease and brain stem lesions should be performed. Concomitant CSVT is rare and might mislead. Fine diagnosis followed by immediate conservative treatment can be of great benefit.
