interleukin il a multilineage hematopoietic growth factor is implicated in the regulation of osteoclastogenesis however the role of il in osteoclastogenesis remains controversial whereas early studies showed that il stimulates osteoclastogenesis recent investigations demonstrated that il inhibits OCL formation the objective of this work is to further address the role of il in osteoclastogenesis we found that il treatment of bone marrow cells generated a population of cells capable of differentiating into osteoclasts in tissue culture dishes in response to the stimulation of the monocytemacrophagecolony stimulating factor mcsf and the receptor activator of nuclear factor kappa b ligand rankl the ildependent hematopoietic cells were able to further proliferate and differentiate in response to mcsf stimulation and the resulting cells were also capable of forming osteoclasts with mcsf and rankl treatment interestingly il inhibits mcsfranklinduced differentiation of the ildependent hematopoietic cells into osteoclasts the FC analysis indicates that while il treatment of bone marrow cells slightly affected the percentage of OCL precursors in the surviving populations it considerably increased the percentage of OCL precursors in the populations after subsequent mcsf treatment moreover osteoclasts derived from ildependent hematopoietic cells were fully PET thus we conclude that il plays dual roles in osteoclastogenesis by promoting the OD of osteoclast progenitors but inhibiting the osteoclastogenic process these findings provide a better understanding of the role of il in osteoclastogenesis | MEDAL |

OT is a rare movement disorder characterized by tremulousness of the lower limbs on standing that disappears on walking sitting or on lying down and a distinctive electromyographic burst of to hz on inspection fine ripples can sometimes be seen over the quadriceps on standing the tremor has a tendency to reappear even in the supine posture if the lower limb muscles are put to an isometric contraction state indicating thereby that in spite of the fact that the tremor occurs on standing it is essentially orthostasis independent and the central factor is the contraction of the muscles as a matter of fact the tremor is abolished if the subject is suspended by harness thus relieving him of muscle contraction doubts are being cast whether it is a variant of essential tremor since a number of families are being reported to be suffering from this disease as well positron emission tomography reveals hyperactivity of cerebellum in orthostatic tremor as it shows in essential tremor therefore lending credence to such a hypothesis however lack of response to alcohol propranolol and primidone in OT stands out as a serious challenge to such a view lack of positive family PH synchrony of contracting group of muscles and negative resetting of the tremor by increasing IP loadphenomena consistently observed in orthostatic tremor and not in essential tremor are other features that often help to distinguish between the two conditions we report a case of orthostatic tremor that presented with the classical clinical and electromyographic features relevant literature in this regard is also being reviewed | MEDAL |

the endoplasmic reticulum er is a major site of protein synthesis in eukaryotes newly synthesized proteins are monitored by a process of SQ control which removes misfolded or unassembled polypeptides from the er for Kd by the proteasome this requires the retrotranslocation of the misfolded proteins from the er lumen into the cytosol via a pathway that for some substrates involves members of the recently discovered derlin family the derlin isoform is present as a dimer in the er and we now show that its dimerization is modulated by er AS three distinct types of chemicallyinduced er stress substantially reduce the levels of derlin dimer as assayed by both crosslinking and coimmunoprecipitation the potential function of the different derlin populations with respect to er SQ control is investigated by analysing their capacity to associate with a misfolded membrane protein fragment we show for the first time that derlin can associate with an aberrant membrane protein fragment in the absence of the viral component us and conclude that it is the monomeric form of derlin that interacts with this potential erassociated degradation substrate on the basis of these data we propose a model where the pool of AS derlin in the er membrane can be modulated in response to er AS | MEDAL |

V1 reconstructions in heavily contaminated fields can be particularly challenging prosthetic grafts are rarely suitable because of the risk of infection but the saphenous vein is usually too small for isodiametric replacement of large arteries and veins although surgeons rarely consider the use of spiral vein grafts they may occasionally be the ideal autogenous vascular replacement because they can be tailored to fit a vessel of any size we report the use of spiral vein grafts in three patients requiring V1 reconstructions in the presence of heavy bacterial contamination | MEDAL |

protein or clara cell protein cc is a kd protein secreted predominantly by clara cells in terminal bronchioles and from puberty on in the male urogenital tract the sensitivity of cc in urine as an index of proximal tubule dysfunction was compared to that of retinolbinding protein beta microglobulin and alpha microglobulin these microproteins were measured by latex immunoassay in the urine from Pr women diabetics men and women workers exposed to Cd men and women and from HS matched for age and sex in women cc appeared consistently as a much more sensitive index of tubular dysfunction than other microproteins in female diabetics for instance the prevalence of elevated values of cc in urine largely exceeded that of other microproteins and even of albumin in men however the existence of a postrenal secretion contaminating the urine limits the sensitivity of cc which was revealed to be higher than that of other microproteins in diabetics only the assay of urinary cc has the potential especially in women to detect very subtle defects of the S3 which pass completely unseen with other microproteins we postulate that this unique sensitivity of cc is due to its very low concentration in TF which combined with its anionic character strongly hinders its access to brush border IB sites | MEDAL |
