"ottoman street" in America: Turkish leatherworkers in peabody, Massachusetts
This article examines the role of Turkish leatherworkers in New Englands labor movement in the early twentieth century. It begins with the exodus of a large Ottoman population from eastern Anatolian provinces to eastern Massachusetts, and their employment in New Englands leather factories. Throughout the article, the rise of the leather business in eastern Massachusetts cities (including Peabody and Salem), the Turkish immigrants concentration on Peabodys Walnut Street (which came to be called Ottoman Street), the importance of kin and friends in providing practical information vital for adjusting to the new environment, and the coffee house as a response to industrial conditions are discussed at length. The author argues that, although many of the Turkish leatherworkers originated from rural backgrounds and had no experience in unionizing and striking, their quick adjustment to the industrial city and their growing awareness of labor rights was a result of lectures given within the Turkish community, changing circumstances in the old country and in the United States, such as the Balkan Wars and World War I, and their unchallenged place in the tanneries of Peabody, MA. © 2009 Copyright Internationaal Instituut voor Sociale Geschiedenis
Kolesistektomi esnasında laparoskopik cerrahiden açık cerrahiye geçişi etkileyen risk faktörleri
Objective: Laparoscopic cholecystectomy has obvious advantages
over open surgery, such as shorter hospital stay, lower morbidity, better
cosmetic results and faster return to daily activities. However, in some
cases, conversion to open technique may be inevitable for patient safety
or for the management of complications having occurred. Although
various risk factors have been identified in many studies, variables such
as technical facilities, surgical technique and experience affect risk
factors. Our study aims to identify these risk factors.
Method: In this study, 2,483 cholecystectomy cases performed in
the general surgery clinic of our hospital between December 2013
and 2016 were retrospectively analyzed. 110 cholecystectomy cases
initiated with open surgery and performed during another operation
were excluded from the study, and 88 patients who were started
laparoscopic surgery and converted to open surgery were selected for
the study. Information on the demographic and clinical characteristics
of the patients was obtained from hospital records. The data of an equal
number of consecutively selected patients from the patients who were
completed laparoscopically were obtained and compared, and whether
these factors had a significant effect on conversion to open surgery was
evaluated.
Results: The rate of conversion from laparoscopic cholecystectomy
to open surgery was 3.7%. The most common reason for conversion
to open surgery was adhesion due to inflammation (n=65, 73.9%).
While male gender, advanced age, diabetes, median incision above
the umbilicus, multiple millimetric calculus and increased wall
thickness in ultrasonography had a significant effect on the conversion
to open surgery (p<0.001), there was no significant correlation with
body mass index, pancreatitis, cholangitis, endoscopic retrograde
cholangiopancreatography or abdominal surgery, anesthesia evaluation score and laboratory values (p>0.05). The durations of hospitalization
and operation were found to be significantly longer in the open group
(p<0.001).
Conclusion: Male gender, advanced age, presence of diabetes, presence
of supra-umbilical median incision, multiple millimetric calculus and
increased wall thickness in ultrasonography are associated with increased
rates of conversion from laparoscopic cholecystectomy to open surgery.
If the coexistence of parameters that we find significant is detected in
the preoperative period, it may be possible to take precautions such as
involving the experienced surgical team in the operation, planning the
operating room, and providing more detailed information to the patient.Amaç: Laparoskopik kolesistektominin, ameliyat sonrası daha kısa
hastanede kalış süresi, daha düşük morbidite, daha iyi kozmetik
sonuçlar ve günlük aktivitelere daha hızlı dönebilme sağlaması gibi
avantajları ile açık cerrahiye göre üstünlüğü aşikardır. Ancak bazı
durumlarda açık tekniğe geçmek hasta güvenliği veya meydana gelmiş
olan komplikasyonu yönetmek için kaçınılmaz olabilmektedir. Birçok
çalışmada çeşitli risk faktörleri tanımlanmış olsa da teknik imkanlar,
cerrahi teknik ve tecrübe gibi değişkenler risk faktörlerini etkilemektedir.
Çalışmamız bu risk faktörlerinin tespit edilmesini amaçlamaktadır.
Yöntem: Çalışmada Aralık 2013-2016 tarihleri arasında hastanemiz
genel cerrahi kliniğinde gerçekleştirilmiş 2,483 kolesistektomi olgusu
retrospektif olarak incelenmiştir. Açık cerrahiyle başlanan ve başka
bir operasyon sırasında uygulanan 110 kolesistektomi olgusu çalışma
dışı bırakılarak, laparoskopik başlayıp açık cerrahiye geçilen 88 hasta
araştırma için seçilmiştir. Hastaların demografik ve klinik özelliklerine ait
bilgiler hastane kayıtlarından elde edilmiştir. Laparoskopik tamamlanan
hastalardan ardışık seçilen eşit sayıda hastanın verileri elde edilerek
karşılaştırılmış, bu faktörlerin açığa geçişe anlamlı etkisi olup olmadığı
değerlendirilmiştir.
Bulgular: Laparoskopik kolesistektomiden açığa geçiş oranı %3,7, en
sık açığa geçiş nedeni ise enflamasyona bağlı adezyon (n=65, %73,9)
olarak bulunmuştur. Açığa geçiş üzerine erkek cinsiyet, ileri yaş, diyabet,
göbek üstü medyan kesi, ultrasonografide multipl milimetrik kalkül
ve duvar kalınlık artışı olmasının anlamlı etkisi olduğu tespit edilirken
(p<0,001), vücut kitle indeksi, pankreatit, kolanjit, endoskopik retrograd
kolanjiopankreatikografi ya da batın operasyonu geçirmiş olma öyküsü,
anestezi değerlendirme skoru ve laboratuvar değerleri ile anlamlı ilişki
tespit edilmemiştir (p>0,05). Yatış ve operasyon süreleri açığa geçilen
grupta anlamlı olarak daha uzun bulunmuştur (p<0,001). Sonuç: Erkek cinsiyet, ileri yaş, diyabet varlığı, göbek üstü medyan kesi
varlığı, ultrasonografide multipl milimetrik kalkül ve duvar kalınlık artışı
olması artmış açığa geçiş oranları ile birliktedir. Anlamlı bulduğumuz
parametrelerin birlikteliğinin preoperatif dönemde tespit edilmesi
halinde zor kolesistektomi olabileceği ve açığa geçiş riskinin artabileceği
düşünülerek eğitim olgusu olarak seçilmeyerek tecrübeli cerrahi ekibin
ameliyata dahil edilmesi, ameliyathanenin planlanması, hastaya daha
ayrıntılı bilgi verilmesi gibi önlemleri almamız mümkün olabilmektedir
Outposts of an Empire : early Turkish migration to Peabody, Massachusetts
Cataloged from PDF version of article.This thesis examines early (1890s-1920s) Turkish immigration to Peabody,
Massachusetts. It is a case study which argues that the most prominent factor driving
early Turkish migration to Peabody was economic. Thus the migration movement
constituted a “brawn drain” from Anatolia to the “streets paved with gold.” As was
the case with some European peoples who immigrated to the United States at the
same period, the Turkish immigrants in Peabody, Massachusetts, did not intend to
stay in the United States. They only wanted to earn money and return to the
homeland as soon as possible. More importantly this thesis argues that the Turkish
immigrants were part of a larger Ottoman migration to the United States. The Turks
in Peabody were part of a chain of migration that included Armenians, Greeks, and
Sephardic Jews. They, together with the Armenians, Jews and Greeks constructed an
Ottoman microcosm in Peabody essentially recreating the millets of the Ottoman
Empire in which inter-communal support helped the Turks contend with the strange
new environment. By the early 1930s most of the Turkish immigrants in Peabody
had returned to their homeland. Overall, this thesis provides new insight into the
Turkish and Ottoman diaspora that challenges popular conceptions of continual strife
between the Turks and members of the other Ottoman millets. Additionally, it shows
that this early Turkish immigrant community was, in some ways, strikingly similar to
later twentieth century Turkish immigrant communities, such as those in Germany
during the 1960sAcehan, IşılM.S

Evaluation of scoring systems in terms of early prediction of severe acute pancreatitis and mortality in patients over 65 years of age.
Purpose: The aim of this study is to investigate the power of disease severity scores to predict the development of Severe Acute Pancreatitis (SAP) and mortality in the early period over 65 years old diagnosed with acute pancreatitis in the emergency department.
Materials and Methods: We calculated RANSON (on admission) and Computed Tomography Severity Index (CTSI) in addition to Bedside Index for Severity in Acute Pancreatitis (BISAP) score on admission to the emergency department.
Results: One hundred and sixty patients (46.9% over 80 years of age) were included in the study. We observed statistically higher length of hospitalization, longer duration of stay in the intensive care unit, SAP and higher mortality in patients over 80 years of age. When we examined the ROC curve, we determined that the AUC values of the BISAP score were highest in both SAP and mortality estimation (AUC: 0.911, 95% CI 0.861-0.962; AUC: 0.918, 95% CI 0.864-0.9722, respectively). Binary logistic analysis indicated a 4.7-fold increased risk for SAP and a 12.3-fold increased mortality for each unit increase in BISAP score value.
Conclusion: BISAP may be a good predictor for SAP and mortality estimation on admission to the emergency department in patients over 65 years of age with acute pancreatitis
The dynamics of cardiolipin synthesis post-mitochondrial fusion
AbstractAlteration in mitochondrial fusion may regulate mitochondrial metabolism. Since the phospholipid cardiolipin (CL) is required for function of the mitochondrial respiratory chain, we examined the dynamics of CL synthesis in growing Hela cells immediately after and 12h post-fusion. Cells were transiently transfected with Mfn-2, to promote fusion, or Mfn-2 expressing an inactive GTPase for 24h and de novo CL biosynthesis was examined immediately after or 12h post-fusion. Western blot analysis confirmed elevated Mfn-2 expression and electron microscopic analysis revealed that Hela cell mitochondrial structure was normal immediately after and 12h post-fusion. Cells expressing Mfn-2 exhibited reduced CL de novo biosynthesis from [1,3-3H]glycerol immediately after fusion and this was due to a decrease in phosphatidylglycerol phosphate synthase (PGPS) activity and its mRNA expression. In contrast, 12h post-mitochondrial fusion cells expressing Mfn-2 exhibited increased CL de novo biosynthesis from [1,3-3H]glycerol and this was due to an increase in PGPS activity and its mRNA expression. Cells expressing Mfn-2 with an inactive GTPase activity did not exhibit alterations in CL de novo biosynthesis immediately after or 12h post-fusion. The Mfn-2 mediated alterations in CL de novo biosynthesis were not accompanied by alterations in CL or monolysoCL mass. [1-14C]Oleate incorporation into CL was elevated at 12h post-fusion indicating increased CL resynthesis. The reason for the increased CL resynthesis was an increased mRNA expression of tafazzin, a mitochondrial CL resynthesis enzyme. Ceramide-induced expression of PGPS in Hela cells or in CHO cells did not alter expression of Mfn-2 indicating that Mfn-2 expression is independent of altered CL synthesis mediated by elevated PGPS. In addition, Mfn-2 expression was not altered in Hela cells expressing phospholipid scramblase-3 or a disrupted scramblase indicating that proper CL localization within mitochondria is not essential for Mfn-2 expression. The results suggest that immediately post-mitochondrial fusion CL de novo biosynthesis is “slowed down” and then 12h post-fusion it is “upregulated”. The implications of this are discussed

Nuclear translocation of cytochrome c during apoptosis
Release of cytochrome c from mitochondria is a major event during apoptosis. Released cytochrome c has been shown to activate caspase-dependent apoptotic signals. In this report, we provide evidence for a novel role of cytochrome c in caspase-independent nuclear apoptosis. We showed that cytochrome c, released from mitochondria upon apoptosis induction, gradually accumulates in the nucleus as evidenced by both immunofluorescence and subcellular fractionation. Parallel to nuclear accumulation of cytochrome c, acetylated histone H2A, but not unmodified H2A, was released from the nucleus to the cytoplasm. Addition of purified cytochrome c to isolated nuclei recapitulated the preferential release of acetylated, but not deacetylated, histone H2A. Cytochrome c was also found to induce chromatin condensation. These results suggest that the nuclear accumulation of cytochrome c may be directly involved in the remodeling of chromatin. Our results provide evidence of a novel role for cytochrome c in inducing nuclear apoptosis
Barth syndrome: an X-linked cause of fetal cardiomyopathy and stillbirth
OBJECTIVE: Barth Syndrome (BTHS) is an X-linked multisystem disorder (OMIM 302060) usually diagnosed in infancy and characterized by cardiac problems [dilated cardiomyopathy (DCM) ± endocardial fibroelastosis (EFE) ± left ventricular non-compaction (LVNC)], proximal myopathy, feeding problems, growth retardation, neutropenia, organic aciduria and variable respiratory chain abnormalities. We wished to determine whether BTHS had a significant impact on fetal and perinatal health in a large cohort of family groups originating from a defined region. METHOD: Case note review on 19 families originating from the UK and known to the Barth Syndrome Service of the Bristol Royal Hospital for Children. RESULTS: Details are presented on six kindreds (32%) with genetically and biochemically proven BTHS that demonstrate a wider phenotype including male fetal loss, stillbirth and severe neonatal illness or death. In these families, 9 males were stillborn and 14 died as neonates or infants but there were no losses of females. BTHS was definitively proven in five males with fetal onset of DCM ± hydrops/EFE/LVNC. CONCLUSION: These findings stress the importance of considering BTHS in the differential diagnosis of unexplained male hydrops, DCM, EFE, LVNC or pregnancy loss, as well as in neonates with hypoglycemia, lactic acidosis and idiopathic mitochondrial diseas
Structural Features of Caspase-Activating Complexes
Apoptosis, also called programmed cell death, is an orderly cellular suicide program that is critical for the development, immune regulation and homeostasis of a multi-cellular organism. Failure to control this process can lead to serious human diseases, including many types of cancer, neurodegenerative diseases, and autoimmununity. The process of apoptosis is mediated by the sequential activation of caspases, which are cysteine proteases. Initiator caspases, such as caspase-2, -8, -9, and -10, are activated by formation of caspase-activating complexes, which function as a platform to recruit caspases, providing proximity for self-activation. Well-known initiator caspase-activating complexes include (1) DISC (Death Inducing Signaling Complex), which activates caspases-8 and 10; (2) Apoptosome, which activates caspase-9; and (3) PIDDosome, which activates caspase-2. Because of the fundamental biological importance of capases, many structural and biochemical studies to understand the molecular basis of assembly mechanism of caspase-activating complexes have been performed. In this review, we summarize previous studies that have examined the structural and biochemical features of caspase-activating complexes. By analyzing the structural basis for the assembly mechanism of the caspase-activating complex, we hope to provide a comprehensive understanding of caspase activation by these important oligomeric complexes
