Degreed and Nondegreed Licensed Clinical Social Workers: An Exploratory Study

This exploratory study focuses on 155 randomly selected respondents who obtained a clinical license in social work with or without the Master of Social Work (MSW) degree. Ninety-seven of the respondents obtained a license with an MSW degree;fifty-eight obtained a license without the MSW degree. The two groups of respondents completed a survey instrument that explored their basic demographic characteristics, their attitudes and behaviors related to practice, and their philosophical and political attitudes toward practice. The researchers found few statistically significant differences between the two groups of respondents. The article offers implications of these findings for the profession of social work

Symbolic Violence and Social Control in the Post-Total Institution Era

Subsequent to the passage of the Community Mental Health Act in 1963, the Total Institutions described by Goffman have for the most part disappeared. Nonetheless, many writers charge that social control is still the primary function of mental health programs, even those that are identified as community-based. The new methods of control have not received widespread attention. In community-based programs control is operationalized in the form of symbolic violence. This paper examines the various factors that contribute to this style of violence

Intra- and inter-hemispheric effective connectivity in the human somatosensory cortex during pressure stimulation

Background: Slow-adapting type I (SA-I) afferents deliver sensory signals to the somatosensory cortex during low-frequency (or static) mechanical stimulation. It has been reported that the somatosensory projection from SA-I afferents is effective and reliable for object grasping and manipulation. Despite a large number of neuroimaging studies on cortical activation responding to tactile stimuli mediated by SA-I afferents, how sensory information of such tactile stimuli flows over the somatosensory cortex remains poorly understood. In this study, we investigated tactile information processing of pressure stimuli between the primary (SI) and secondary (SII) somatosensory cortices by measuring effective connectivity using dynamic causal modeling (DCM). We applied pressure stimuli for 3 s to the right index fingertip of healthy participants and acquired functional magnetic resonance imaging (fMRI) data using a 3T MRI system. Results: DCM analysis revealed intra-hemispheric effective connectivity between the contralateral SI (cSI) and SII (cSII) characterized by both parallel (signal inputs to both cSI and cSII) and serial (signal transmission from cSI to cSII) pathways during pressure stimulation. DCM analysis also revealed inter-hemispheric effective connectivity among cSI, cSII, and the ipsilateral SII (iSII) characterized by serial (from cSI to cSII) and SII-level (from cSII to iSII) pathways during pressure stimulation. Conclusions: Our results support a hierarchical somatosensory network that underlies processing of low-frequency tactile information. The network consists of parallel inputs to both cSI and cSII (intra-hemispheric), followed by serial pathways from cSI to cSII (intra-hemispheric) and from cSII to iSII (inter-hemispheric). Importantly, our results suggest that both serial and parallel processing take place in tactile information processing of static mechanical stimuli as well as highlighting the contribution of callosal transfer to bilateral neuronal interactions in SII.open1

Pig-to-Nonhuman Primate (NHP) Naked Islet Xenotransplantation

Islet transplantation is an established therapy for selected type 1 diabetes (T1D) patients with severe hypoglycemic unawareness and glycemic liability despite of insulin treatment. However, the donor organ is limited. Porcine islets are the best alternative source to overcome this limitation, and pig-to-nonhuman primate (NHP) naked islet xenotransplantation studies are being performed worldwide. Several studies including our own have presented successful proof-of-concept results based on immunosuppression regimen including the anti-CD154 monoclonal antibody. Particularly, long-term control of diabetes by adult porcine islet transplantation has been demonstrated in five consecutive monkeys, and the longest survival was ~1000 days after transplantation. Currently, pig-to-NHP islet xenotransplantation based on clinically applicable immunosuppression regimen is being pursued. In this chapter, we will describe all the procedures of pig-to-NHP naked islet xenotransplantation: (1) the porcine islet isolation from designated pathogen-free (DPF) miniature pigs, (2) diabetes induction in monkeys, (3) transplantation procedure via the portal vein, (4) immune monitoring comprising humoral and cellular immunity after porcine islet transplantation, and finally (5) liver biopsy and subsequent immunohistochemical procedure in detail

Interferometric detection of prostate specific antigen based on enzyme immunoassay

AbstractInterferometric detection of Prostate-specific antigen (PSA) based on enzyme immunoassay are investigated. Refractive index changes of substrate are measured for PSA detection. Michelson scheme of optical interferometer was used so as to be applicable to a disposable fluidic chip. When interferometer is used for the measurements of refractive index changes, the detection is over 8 times more sensitive than that of absorbance changes for the same amount of target protein

Unusual Presentation of Cystic Lymphangioma of the Gallbladder

Cystic lymphangioma of the gallbladder is quite a rare tumor with only a few cases having been reported in the literature. We describe here a rare case of cystic lymphangioma of the gallbladder, which was unusual in that the patient presented with biliary pain and an abnormal liver test. Ultrasonography and computed tomography of the abdomen showed a multi-septated cystic mass in the gallbladder fossa and an adjacent compressed gallbladder. Endoscopic retrograde cholangiography showed there was no communication between the bile tract and the lesion, and there were no other abnormal findings with the exception of a laterally compressed gallbladder. After performing endoscopic sphincterotomy, a small amount of sludge was released from the bile duct. The histological findings were consistent with a cystic lymphangioma originating from the subserosal layer of the gallbladder. This unusual clinical presentation of a gallbladder cystic lymphangioma was attributed to biliary sludge, and this was induced by gallbladder dysfunction that was possibly from compression of the gallbladder due to the mass

An additional cysteine in a typical 2-Cys peroxiredoxin of Pseudomonas promotes functional switching between peroxidase and molecular chaperone

AbstractPeroxiredoxins (Prx) have received considerable attention during recent years. This study demonstrates that two typical Pseudomonas-derived 2-Cys Prx proteins, PpPrx and PaPrx can alternatively function as a peroxidase and chaperone. The amino acid sequences of these two Prx proteins exhibit 93% homology, but PpPrx possesses an additional cysteine residue, Cys112, instead of the alanine found in PaPrx. PpPrx predominates with a high molecular weight (HMW) complex and chaperone activity, whereas PaPrx has mainly low molecular weight (LMW) structures and peroxidase activity. Mass spectrometry and structural analyses showed the involvement of Cys112 in the formation of an inter-disulfide bond, the instability of LMW structures, the formation of HMW complexes, and increased hydrophobicity leading to functional switching of Prx proteins between peroxidase and chaperone
