Abstract
The current work focuses on the synthesis of hybrid nanoparticles (NPs) made of a silica core (Si NPs) coated with discrete gold nanoparticles (Au NPs), which exhibit localized surface plasmon resonance (LSPR) properties. This plasmonic effect is directly related to the nanoparticles size and arrangement. In this paper, we explore a wide range of size for the silica cores (80, 150, 400, and 600 nm) and for the gold NPs (8, 10, and 30 nm). Some rational comparison between different functionalization techniques and different synthesis methods for the Au NPs are proposed, related to the optical properties and colloidal stability in time. An optimized, robust and reliable synthesis route is established, which improves the gold density and homogeneity. The performances of these hybrid nanoparticles are evaluated in order to be used in the shape of a dense layer for pollutant detection in gas or liquids, and find numerous applications as a cheap and new optical device.

Abstract
Bckground and Objectives EUS-guided cystogastrostomy is a well-established advanced endoscopic technique with a steep-learning curve which necessitates an ex-vivo simulator that would allow for adequate training. The aim of this study is to evaluate the feasibility of the model in allowing training for EUS-guided cystogastrostomy using lumen-apposing metal stent (LAMS). Subjects and Methods The model was created by ROEYA Training Center, Egypt, using native porcine tissue to create fluid collections simulating both cystic and solid lesions. It was designed and tested in advance while the hydrogel was added on-site. The simulator was evaluated prospectively in five training sessions involving 17 international experts. The task was to successfully deploy the LAMS to drain the created cyst. After using the simulator, the experts were asked to fill a questionnaire to assess their experience. The primary endpoint was overall satisfaction with the model as a training tool. Results All of the experts were satisfied with the model as a tool to train endoscopists for the technique. 76.5% (n = 11) of the experts thought the model to be moderately realistic. Proper visualization was reported by 94.1% of the experts. All experts believed the lesions to be either slightly like or very similar to real lesions. The model was graded "easy" in difficulty by 11 of the experts. Conclusions In all parameters assessed, the experts thought the model to be a useful tool for future training. This preliminary study suggests that the aforementioned simulator can be used to train endoscopists on using LAMS in a risk-free environment.

Abstract
BackgroundWhile CAR-T have demonstrated potent activity against hematologic tumors, less success has been seen with solid tumors. Here we report generation of TSCM-enriched allogeneic MUC1-C-specific CAR T cells, P-MUC1C-ALLO1, with potential for a broad range of solid tumors. The proliferative capacity and metabolic profile of TSCM CAR-T are well-suited to activity in the solid tumor setting. MUC1 is comprised of an N-terminal subunit (MUC1-N) tethered to a C-terminal subunit (MUC1-C), forming a stable complex on the cell surface. During tumorigenesis, MUC1 becomes both overexpressed and hypo-glycosylated on many carcinomas. Furthermore, MUC1 undergoes proteolytic cleavage in the tumor microenvironment, leaving behind a proteolytic ‘stump’ of MUC1-C that is over-represented in cancer, making it an attractive therapeutic target.MethodsP-MUC1C-ALLO1 is manufactured using the piggyBac® DNA Delivery System for CAR insertion and the Cas-CLOVER™ Gene Editing System to knockout both the TCR and MHC class I proteins. The addition of a selectable marker within the transposon allows for selection of a fully CAR-positive population while any residual TCR-positive cells are removed at the end of production to prevent TCR-mediated GvHD. Lastly, inclusion of a proprietary ‘booster molecule’ in our allogeneic process further improves cell expansion, along with phenotype and function, and enables the production of up to hundreds of patient doses from a single manufacturing run.ResultsSignificant doses of P-MUC1C-ALLO1 products made from multiple healthy donors were achieved and comprised of an exceptionally high-percentage of desirable TSCM cells. Preclinical evaluation of these products showed potent tumor killing and cytokine secretion against MUC1-C-positive breast and ovarian tumor cell lines. P-MUC1C-ALLO1 demonstrates potent cytotoxicity against tumor cells, and minimal killing of normal MUC1-C-positive human primary cells. In a triple negative breast cancer xenograft model, MUC1C CAR-T eliminated established MDA-MB-468 tumor cells, mounted robust T cell expansion in peripheral blood and maintained a favorable TSCM percentage over time. Likewise, in an orthotopic ovarian cancer xenograft model, intraperitoneally administered MUC1C CAR-T eliminated established OVCAR3 cells to levels below the limit of detection. All together, these data demonstrated the efficacy of the MUC1C CAR-T cells and the robustness of the allogeneic platform.ConclusionsP-MUC1C-ALLO1 is an allogeneic TSCM CAR-T therapy that has a potential to treat multiple MUC1-expressing indications. P-MUC1C-ALLO1 displayed specificity for tumor vs. normal cells as well as in vivo efficacy against xenograft models of breast and ovarian cancer. This allogeneic cell therapy is advancing rapidly towards the clinic.

Abstract
Natural killer (NK) cells are known to target cancer stem cells and undifferentiated tumors. In this paper, we provide a novel strategy for expanding large numbers of super-charged NK cells with significant potential to lyse and differentiate cancer stem cells and demonstrate the differences in the dynamics of NK cell expansion between healthy donors and cancer patients. Decline in cytotoxicity and lower interferon (IFN)-γ secretion by osteoclast (OC)-expanded NK cells from cancer patients correlates with faster expansion of residual contaminating T cells within purified NK cells, whereas healthy donors’ OCs continue expanding super-charged NK cells while limiting T cell expansion for up to 60 days. Similar to patient NK cells, NK cells from tumor-bearing BLT-humanized mice promote faster expansion of residual T cells resulting in decreased numbers and function of NK cells, whereas NK cells from mice with no tumor continue expanding NK cells and retain their cytotoxicity. In addition, dendritic cells (DCs) in contrast to OCs are found to promote faster expansion of residual T cells within purified NK cells resulting in the decline in NK cell numbers from healthy individuals. Addition of anti-CD3 mAb inhibits T cell proliferation while enhancing NK cell expansion; however, expanding NK cells have lower cytotoxicity but higher secretion of IFN-γ. Expansion and functional activation of super-charged NK cells by OCs is dependent on interleukin (IL)-12 and IL-15. Thus, in this report, we not only provide a novel strategy to expand super-charged NK cells, but also demonstrate that rapid and sustained expansion of residual T cells within the purified NK cells during expansion with DCs or OCs could be a potential mechanism by which the numbers and function of NK cells decline in cancer patients and in BLT-humanized mice.

Abstract
Injury to the barrier tissue initiates a rapid distribution of myeloid immune cells from bone marrow, which guide sound wound healing. Bisphosphonates, a widely used anti-bone resorptive drug with minimal systemic side effects, have been linked to an abnormal wound healing in the oral barrier tissue leading to, in some cases, osteonecrosis of the jaw (ONJ). Here we report that the development of ONJ may involve abnormal phenotypic plasticity of Ly6G+/Gr1+ myeloid cells in the oral barrier tissue undergoing tooth extraction wound healing. A bolus intravenous zoledronate (ZOL) injection to female C57Bl/6 mice followed by maxillary first molar extraction resulted in the development of ONJ-like lesion during the second week of wound healing. The multiplex assay of dissociated oral barrier cells exhibited the secretion of cytokines and chemokines, which was significantly modulated in ZOL mice. Tooth extraction-induced distribution of Ly6G+/Gr1+ cells in the oral barrier tissue increased in ZOL mice at week 2. ONJ-like lesion in ZOL mice contained Ly6G+/Gr1+ cells with abnormal size and morphology as well as different flow cytometric staining intensity. When anti-Ly6G (Gr1) antibody was intraperitoneally injected for 5 days during the second week of tooth extraction, CD11b+GR1(hi) cells in bone marrow and Ly6G+ cells in the oral barrier tissue were depleted, and the development of ONJ-like lesion was significantly attenuated. This study suggests that local modulation of myeloid cell plasticity in the oral barrier tissue may provide the basis for pathogenesis and thus therapeutic as well as preventive strategy of ONJ.

Abstract
INTRODUCTION The previously performed studies showed that the presence of colorectal cancer (CRC) tumor is associated with the atrophy of myenteric plexuses in the vicinity of cancer invasion; however, the possible mechanisms of this phenomenon are not known. The aim of the present study was to determine whether the atrophic changes of the enteric nervous system (ENS) within an intestine wall of the CRC patients were caused by apoptosis or necrosis and whether they were associated with changes in the number of galanin-immunore-active (GAL-Ir) neurons. MATERIAL AND METHODS Samples of the large intestine wall located close to the CRC invasion and control, distally-located part of the colon, were collected from 9 CRC patients. The size of ENS plexuses and the number of neurons were compared. Triple immunofluorescent staining was used to visualize the co-expression of caspase 3 (CASP3) or caspase 8 (CASP8) with GAL and protein gene-product 9.5 (PGP 9.5, panneuronal marker) in the submucosal and myenteric ENS plexuses. The cells expressing myeloperoxidase (MPO, marker of neutrophils) and CD68 (marker of macrophages) were detected by immunohistochemistry around/in myenteric plexuses (MPs) and in the muscularis externa of the colon wall in the vicinity of tumor invasion. RESULTS Myenteric plexuses in the vicinity of the CRC tissue were significantly smaller and had lower number of neurons per plexus than distantly located plexuses. The number of CASP8- and CASP3-Ir neurons in the ENS plexuses was similar in the colon wall both close to and distally from tumor invasion. The number of CASP8-Ir neurons within MPs located close to CRC invasion was higher than of CASP3-Ir neurons. The percentage of neurons co-expressing CASP8 and GAL in myenteric plexuses close and distantly from tumor was three-fold lower than of those co-expressing CASP3 and GAL. The mean number of neutrophils and macrophages inside and around myenteric plexuses located close to tumor invasion was higher or similar, respectively, as compared with adjacent muscularis externa. CONCLUSIONS The atrophy of myenteric plexuses in the vicinity of CRC invasion is not caused by apoptosis or necrosis. The differences in the proportions of neurons expressing galanin and the studied caspases suggest as yet unknown role of this neuropeptide in the mechanisms of neuron's atrophy in MPs located close to CRC tumor.

Abstract
The aim of this study is to establish osteoclasts as key immune effectors capable of activating the function of Natural Killer (NK) cells, and expanding their numbers, and to determine in vivo and in vitro effect of bisphosphonates (BPs) during NK cell interaction with osteoclasts and on systemic and local immune function. The profiles of 27 cytokines, chemokines and growth factors released from osteoclasts were found to be different from dendritic cells and M1 macrophages but resembling to untreated monocytes and M2 macrophages. Nitrogen-containing BPs Zoledronate (ZOL) and Alendronate (ALN), but not non-nitrogen-containing BPs Etidronate (ETI), triggered increased release of pro-inflammatory mediators from osteoclasts while all three BPs decreased pit formation by osteoclasts. ZOL and ALN mediated significant release of IL-6, TNF-` and IL-1β, whereas they inhibited IL-10 secretion by osteoclasts. Treatment of osteoclasts with ZOL inhibited NK cell mediated cytotoxicity whereas it induced significant secretion of cytokines and chemokines. NK cells lysed osteoclasts much more than their precursor cells monocytes, and this correlated with the decreased expression of MHC class I expression on osteoclasts. Intravenous injection of ZOL in mice induced pro-inflammatory microenvironment in bone marrow and demonstrated significant immune activation. By contrast, tooth extraction wound of gingival tissues exhibited profound immune suppressive microenvironment associated with dysregulated wound healing to the effect of ZOL which could potentially be responsible for the pathogenesis of Osteonecrosis of the Jaw (ONJ). Finally, based on the data obtained in this paper we demonstrate that osteoclasts can be used as targets for the expansion of NK cells with superior function for immunotherapy of cancer.

Abstract
The kynurenine pathway (KP) of L-tryptophan metabolism produces several neuroactive metabolites with an amino acid structure. These metabolites may play an important role in the pathophysiology of irritable bowel syndrome, Alzheimer's disease, Parkinson's disease, Huntington's disease, schizophrenia, AIDS-dementia complex, depression, epilepsy and the aging process. Modulation of the KP through inhibition or stimulation of enzyme synthesis and activity can be an alternative approach to traditional therapy. Furthermore, it may be responsible for the altered functioning of the enteric nervous system and the central nervous system. There is evidence that the KP is sensitive to changes in the concentration of many vitamins and minerals that play a crucial role as coenzymes and cofactors in the de novo synthesis of nicotinamide adenine dinucleotide coenzyme. A reduction in the availability of the active form of vitamin B6 (pyridoxal 5'-phosphate, PLP) is known to affect tryptophan hydroxylase, kynurenine aminotransferase and kynureninase (KYNU). Vitamin B2 deficiencies result in a reduction in the activity of the flavin adenine dinucleotide dependent enzyme, kynurenine 3-monooxygenase. Minerals are also responsible for the proper functioning of enzymes engaged in L-tryptophan metabolism. Mn(2+), Zn(2+), Co(2+) and Cu(2+) influence KYNU activity, and Mg(2+) regulates quinolinate phosphoribosyl transferase. Fe(2+) is responsible for the proper functioning of both indoleamine 2,3-dioxygenase and 3-hydroxy-anthranilic acid dioxygenase. Changes in the concentration of KP metabolites and in enzymatic activity have been found in many pathological states. Therefore, it is justifiable to regulate the concentration of certain kynurenines or enzymes in the KP which may provide a potential therapeutic target for the treatment of various health impairments. This review demonstrates the role of vitamin and mineral activity on the KP, which may have an effect on the proper functioning of the human organism. Surplus administration of vitamins did not elicit any beneficial effects on L-tryptophan metabolism. Whether a mineral surplus influences L-tryptophan metabolism is still not established. It seems that cofactor deficiencies influence the KP far more than surpluses.

Abstract
Our previous reports demonstrated that the magnitude of natural killer (NK) cell-mediated cytotoxicity correlate directly with the stage and level of differentiation of tumor cells. In addition, we have shown previously that activated NK cells inhibit growth of cancer cells through induction of differentiation, resulting in the resistance of tumor cells to NK cell-mediated cytotoxicity through secreted cytokines, as well as direct NK-tumor cell contact. In this report, we show that in comparison to IL-2 + anti-CD16mAb-treated NK cells, activation of NK cells by probiotic bacteria (sAJ2) in combination with IL-2 and anti-CD16mAb substantially decreases tumor growth and induces maturation, differentiation, and resistance of oral squamous cancer stem cells, MIA PaCa-2 stem-like/poorly differentiated pancreatic tumors, and healthy stem cells of apical papillae through increased secretion of IFN-γ and TNF-α, as well as direct NK-tumor cell contact. Tumor resistance to NK cell-mediated killing induced by IL-2 + anti-CD16mAb + sAJ2-treated NK cells is induced by combination of IFN-γ and TNF-α since antibodies to both, and not each cytokine alone, were able to restore tumor sensitivity to NK cells. Increased surface expression of CD54, B7H1, and MHC-I on NK-differentiated tumors was mediated by IFN-γ since the addition of anti-IFN-γ abolished their increase and restored the ability of NK cells to trigger cytokine and chemokine release; whereas differentiated tumors inhibited cytokine release by the NK cells. Monocytes synergize with NK cells in the presence of probiotic bacteria to induce regulated differentiation of stem cells through secretion of IL-10 resulting in resistance to NK cell-mediated cytotoxicity and inhibition of cytokine release. Therefore, probiotic bacteria condition activated NK cells to provide augmented differentiation of cancer stem cells resulting in inhibition of tumor growth, and decreased inflammatory cytokine release.

Abstract
The list of genes, which augment NK cell function when knocked out in neighboring cells is increasing, and may point to the fundamental function of NK cells targeting cells with diminished capability to differentiate optimally since NK cells are able to target less differentiated cells, and aid in their differentiation. In this paper, we aimed at understanding the effect of monocytes from targeted knockout of COX-2 in myeloid cells (Cox-2flox/flox;LysMCre/+) and from control littermates (Cox-2flox/flox;LysM+/+) on ex vivo function of NK cells. Furthermore, we compared the effect of monocytes treated with and without lipopolysaccharide (LPS) on NK cells from mice and humans. NK cells purified from Cox-2flox/flox;LysMCre/+ mice had heightened cytotoxic activity when compared to those obtained from control littermates. In addition, NK cells cultured with autologous Cox-2flox/flox;LysMCre/+ monocytes and DCs, mouse embryonic fibroblasts from global knockout COX-2, but not with knockout of COX-2 in T cells, had increased cytotoxic function as well as augmented IFN-γ secretion when compared to NK cells from control littermates cultured with monocytes. LPS inhibited NK cell cytotoxicity while increasing IFN-γ secretion when cultured in the presence of monocytes from either Cox-2flox/flox;LysMCre/+ or control littermates. In contrast to mice, NK cells from humans when cultured with monocytes lost cytotoxic function and gained ability to secrete large amounts of IFN-γ, a process, which we had previously coined as “split anergy.” Similar to mice, LPS potentiated the loss of human NK cell cytotoxicity while increasing IFN-γ secretion in the presence of monocytes. Greater loss of cytotoxicity and larger secretion of IFN-γ in NK cells induced by gene knockout cells may be important for the greater need of these cells for differentiation.

Abstract
Cancer radiotherapy may be immunogenic, but it is unclear why its immunogenic effects are rarely sufficient to prevent tumor recurrence. Here, we report a novel Toll-like receptor 9 (TLR9)-dependent mechanism that initiates tumor regrowth after local radiotherapy. Systemic inhibition of TLR9, but not TLR4, delayed tumor recurrence in mouse models of B16 melanoma, MB49 bladder cancer, and CT26 colon cancer after localized high-dose tumor irradiation. Soluble factors in the microenvironment of regressing tumors triggered TLR9 signaling in freshly recruited myeloid cells appearing within four days of radiotherapy. The tumorigenic effects of TLR9 depended on MyD88/NF-κB-mediated upregulation of interleukin (IL)-6 expression, which in turn resulted in downstream activation of Jak/STAT3 signaling in myeloid cells. In comparing global gene expression in wild-type, TLR9-, or STAT3-deficient myeloid cells derived from irradiated tumors, we identified a unique set of TLR9/STAT3-regulated genes involved in tumor-promoting inflammation and revascularization. Blocking STAT3 function by two myeloid-specific genetic strategies corrected TLR9-mediated cancer recurrence after radiotherapy. Our results suggest that combining localized tumor irradiation with myeloid cell-specific inhibition of TLR9/STAT3 signaling may help eliminate radioresistant cancers.

Abstract
OBJECTIVE CD4+ T cells from patients with systemic lupus erythematosus (SLE) display defective function that contributes to abnormal activation of B cells and autoantibody production. METHODS We compared the transcript and protein levels of Fyn and CD70 in CD4+ T cells from patients with SLE (n = 41) and healthy individuals (n = 34). The CD4+ T cells were isolated by positive biomagnetic separation technique. The quantitative analysis of messenger RNA was performed by reverse transcription and real-time quantitative PCR. The protein contents in the CD4+ T cells were determined by Western blotting analysis. RESULTS We observed significantly higher levels of Fyn (p = 0.03) and CD70 (p = 0.029) transcripts in SLE CD4+ T cells than in controls. There was a significant increase in CD70 protein levels (p < 0.0001), but not Fyn protein levels (p = 0.081) in CD4+ T cells from patients with SLE compared to healthy individuals. In the group with high disease activity [SLE Disease Activity Index (SLEDAI) >/= 9], we observed a significantly higher Fyn protein content than in controls (p = 0.030). There was no correlation between Fyn and CD70 protein levels in SLE CD4+ T cells and disease activity as expressed in the SLEDAI scale. CONCLUSION We confirmed previous observations of higher expression of CD70 in CD4+ T cells from patients with SLE. Our findings suggest that increased Fyn protein content in CD4+ T cells can be associated with high SLE disease activity.

Abstract
The aim of the study was to compare alterations of various regions of the basement membrane zone (BMZ) in lichen sclerosus (LS) using laser scanning confocal microscopy. The study included three cases of bullous LS, one case of bullous LS that developed in the course of graft-versus-host disease (GVHD), and six cases of non-bullous LS. Three cases of morphea served as a control. Biopsies from patients' skin and control biopsies from normal human skin were cut into 30-microm thick slides and labeled with antibodies against beta4-intergin (lamina lucida marker), collagen IV, and the N-terminal end of collagen VII (lamina densa markers) and the C-terminal end of collagen VII (sublamina densa marker) using routine immunofluorescence (IF). Three-dimensional (3D) reconstruction of various regions of the BMZ showed a decrease in the number and size of the dermal papillae in LS and morphea as compared with normal skin. In LS numerous invaginations and holes were present in the BMZ at the level of the lamina lucida and lamina densa. Computer animation of 3D projections revealed that the thickness of the lamina densa observed under the light microscopy is an optical artifact dependent on periodical tortion of the lamina densa along its axis. Torsions and invaginations of the BMZ are equally responsible for the phenomenon of artificial reduplication of the lamina densa observed at the ultrastructural level. IF labeling with antibody against the N-terminal end of collagen VII disclosed the presence of a large hole (up to 25 microm) in the lamina densa and the presence of granular material in deep dermis suggestive of partial degradation of lamina densa at the level of anchoring fibers. An IF mapping study showed blister formation below the lamina densa in three patients with bullous LS, whereas in a case of LS associated with GVHD, a blister formed through the basal layer of the epidermis. In morphea, there was flattening of BMZ at the level of lamina lucida, lamina densa, and sublamina densa but the continuity of BMZ was preserved. Three-dimensional reconstruction of dermal-epidermal junction in LS revealed alterations of the BMZ, most pronounced at the level of the lamina densa and sublamina densa.

Abstract
We describe a case with clinical and histologic features of pemphigus herpetiformis associated with IgG and IgA anti-keratinocyte cell surface antibodies to desmoglein 1 (Dsg1) and exclusively IgG antibodies to desmocollin 3 (Dsc3). The clinical presentation was somewhat similar to IgA pemphigus; the main difference was the prevailing association with IgG antibodies to Dsg1. The presence of IgA anti-Dsg1 antibodies was confirmed by IgA enzyme-linked immunosorbent assay and IgG anti-Dsc3 antibodies were detected by a novel enzyme-linked immunosorbent assay with the use of baculovirus expressing recombinant Dscs for IgG and IgA. The reactivity of IgG antibodies with Dsc3 was confirmed by COS-7 cell cDNA transfection method using cDNA of human Dsc1 to Dsc3. We discuss the differentiation of pemphigus herpetiformis, associated with both IgG and IgA antibodies, from IgA pemphigus, particularly in regard to the autoimmune reaction with Dsgs and Dscs.

Abstract
We compared HLA antigen expression on new B-lymphoblastoid cell line (B-LCL) HAJ with that on B-LCLs expressing normal HLA levels as well as on B-LCLs derived from bare lymphocyte syndrome (BLS) patients and in vitro mutated B-LCLs of BLS-like phenotype. HAJ cells had no expression of HLA class II and low expression of class I antigens similarly to some of BLS B-LCLs, although HAJ cell line was derived from lymphocytes of HLA class I- and class II-normally expressing donor. HAJ cells displayed B lymphocyte markers, surface immunoglobulin and CD19. Culture of HAJ cells in the presence of interferon y resulted in HLA class I antigen upregulation, but did not restore class II expression. The cell line HAJ may prove useful for studies on factors influencing HLA class I cell surface expression.

Abstract
A 28-year-old man was admitted to our department for investigation in 1992. He presented with a red, scaly, centrifugally spreading eruption, which had appeared in 1990, beginning on the neck and thorax, and later extending to the trunk and limbs. The cutaneous lesions, located mainly on the trunk and proximal upper limbs, were arranged in rings, with a slightly raised prominent scaling edge (Fig. 1a). The characteristic feature was the presence of rings or waves within already existing rings, whereas the central part was flattened, with the texture of normal skin. The concentric figurate lesions resembled a wood grain pattern (Fig. 1b). The clinical picture was strikingly similar to tinea imbricata; there was, however, no itching, and repeated mycologic studies did not disclose Trichophyton concentricum. The histology was not characteristic. The epidermis, which was slightly edematous, was covered with a heavy crust. In the dermis, a sparse inflammatory infiltrate, somewhat more pronounced in the subpapillary areas, was composed of lymphocytes with some eosinophils. Periodic acid-Schiff (PAS) and other stains for mycotic infection were negative. The general condition was not affected and laboratory studies did not show any abnormalities, except for low serum protein (5.1 g/L) and decreased gamma globulins (10.5%). Cell-mediated immunity was preserved. Immunofluorescence studies (direct and indirect) were negative. In spite of repeatedly negative mycotic examinations and due to the striking similarity to tinea imbricata, we applied various antimycotic therapies (terbinafine, itraconazole), with no effect. The figurate pattern, with normal skin in between, altered from day to day, while new concentric rings appeared within the cleared skin. The migrating rate was about 2-3 cm per 2 weeks. The patient had undergone a thorough search for internal malignancy. During the follow-up period of 1992-98, cutaneous involvement slowly became almost generalized (1996), and the confluent lesions formed large plaques, but still with pronounced concentric rings. Transitional blood eosinophilia (27% in 1993 and 11% in 1996) regressed with no therapy. Since 1995, antibodies to HBs and HBc have been present with no clinical symptoms of liver disease. The blood proteins increased to 7.0 g/L, and gamma globulins to 17.2% (normal). The histology, studied repeatedly, started to display some signs of psoriasis from 1996 and, in 1998, was already consistent with the disease (Fig. 2). RE-PUVA (0.8 mg/kg acitretin and UVA 0.8 J/cm2 ) was applied for 2 weeks before the patient interrupted the therapy. In spite of this, there was further improvement and, in 1999, the patient was almost free of lesions with some abortive rings left. From time to time, single vesicles appeared within the elevated borders of the rings. The histology of such vesicles was consistent with abortive pustular psoriasis (Fig. 3).

Abstract
Congenital atrichia with papular lesions is a rare, recessively inherited form of hair loss characterized by a complete absence of all body hair shortly after birth. Mutations in the human ortholog of the mouse hairless (hr) gene have been implicated in the pathogenesis of this disorder. In this study, we screened, by direct sequence analysis, the hairless gene in a family of Polish descent and identified a novel missense mutation (C622G). The mutation alters the third of four invariant cysteins in the zinc-finger domain, which has high homology to the C-X-X-C-(X)17-C-X-X-C structure of the zinc-fingers of the GATA family of transcription factors. The human hairless gene encodes a putative transcription factor with restricted expression in the brain and skin, which is involved in the regulation of apoptosis during catagen remodeling in the hair cycle.

Abstract
The impact of optimal temperature, osmotic pressure, and diet viscosity on the number of mosquitoes (Anopheles stephensi) feeding through a membrane, and on the size of the blood meal, was evaluated. An increase in diet viscosity decreased the number of imbibing mosquitoes, reduced the size of the ingested meal, and resulted in a slower rate of weight loss after feeding. The possible effect of these factors on the vectorial efficiency of mosquitoes is discussed.

Abstract
Hamsters blood infected with Plasmodium berghei was cultured in vitro for the development of ookinetes. The ookinetes were separated from blood components, suspended in various defined media and fed to Anopheles stephensi through a membrane. The development of the oocysts and infective sporozoites was recorded. Mosquitoes infected with ookinetes suspended in L15 formulated into L15-B, L15-D (a medium specially modified for this purpose), IPL-41 or 199 media with no proteins added, developed at least as many oocysts as the control mosquitoes fed ookinetes suspended in blood. Ookinetes suspended in the L15-B medium yielded more oocysts than after feeding ookinetes suspended in L15-B with 5% casein. Sporozoites from mosquitoes maintained on blood, L15-B, L15-D, or L15-B with 5% casein were shown to be infective to hamsters. Mosquitoes fed ookinetes suspended in sucrose solutions showed very few oocysts, but the yield was increased when a blood meal was given 2-4 days after the infective meal. Some of the oocysts which had developed from the ookinetes suspended in artificial media were found to have degenerated. The described system could be potentially useful for a study of the interaction between the vector physiology and the parasite. The possible use of the system to learn which media should be developed in the future for in vitro cultivation of oocysts is discussed.

Abstract
Anopheles stephensi mosquitoes were infected with Plasmodium berghei by feeding on parasitaemic hamsters. After the infective blood meal they were separated into groups that were maintained on sugar solutions containing different additives. The numbers of oocysts developing in the various groups were then compared. When either casein, haemoglobin or foetal bovine serum was added to the sugar, the yield of oocysts was 1.6-2.1 times higher than that in controls fed only on sugar solutions. When either medium 199, Leibovitz's formulated L15 (L15-B) or 'B' compounds alone were added, the yield of oocysts was 2.3-2.9 times higher than that in the controls. The addition of p-aminobenzoic acid, hypoxanthine, methiolnine, or fractions of 'B' had no significant effect on the number of oocysts.

Abstract
The activity of lipoprotein lipase (LPL) from adipose tissue, the postheparin lipolytic activity (PHLA) in plasma, and the content of plasma lipoproteins were investigated in rats poisoned with dichlorvos (DDVP). Administration of a single dose (50% LD50) resulted in inhibition of LPL and PHLA; the greatest inhibition was observed at 24 and 48 h after administration of the posticide. The metabolism of serum lipoproteins was also altered; the content of triacylglycerols in very low density lipoproteins (VLDL) and low density lipoproteins (LDL) fractions was increased; the content of cholesterol was increased in VLDL and high density lipoproteins (HDL) fractions, and decreased in the LDL fraction. On repeated administration of small DDVP doses (5% LD50) the greatest changes were observed after 90 days of intoxication. The levels of all three determined lipoprotein fractions, as well as PHLA, were decreased. The LPL activity in adipose tissue was slightly raised. The results suggest that DDVP interferes with the metabolism of lipids.

Abstract
A series of 250 consecutive patients with dermatitis and positive patch tests to chromate was divided into three groups: nonoccupational dermatitis (94), occupational dermatitis caused by chromate (132) and occupational dermatitis caused by allergens other than chromate (24). Only 17.2% of patients did not report harmful effects from chromium-tanned leather. Shoes were most often not tolerated. The role of matches in the development of chromate dermatitis is discussed. Observations on ash, household detergents, textiles, wood, tattooing, cement, galvanizing solutions, printer's ink, welding fumes, corrosion inhibitors and oils are described as causes of chromate dermatitis in Poland, as well as the localization of dermatitis and relevance of patch test reactions.

Abstract
The frequency of positive patch tests to 13 rubber accelerators in Poland was recorded. Of particular interest was the relatively large group of patients positive to several, mostly chemically unrelated, accelerators. The mechanism of this multiple sensitivity is discussed. Positive tests to N-isopropyl-N-phenyl-p-phenylenediamine were observed in more than half of the patients reacting to several aromatic amines. Anamnesis indicated that in the case of cross-reactions to many aromatic amines, none of the patients positive to N-isopropyl-N-phenyl-p-phenylenediamine had complained of a reaction to rubber products.
