Abstract
Urinary tract infections (UTIs) are highly prevalent bacterial infections that pose significant health risks. Specific probiotic strains have been recommended for UTI control and management of antibiotic resistance. Otherwise, para-probiotics, defined as inactivated probiotic cells, offer potential advantages by minimizing risks associated with live microorganisms. However, the effectiveness of heat-killed probiotic strains against UTIs remains uncertain. Additionally, lactoferrin (LF), an iron-binding glycoprotein, exhibits immunomodulatory, antimicrobial, and anti-inflammatory properties. Recently, we had developed recombinant LF-expression probiotics, which can display considerate antibacterial activities against select food-borne pathogens in vitro. Thus, the present study aimed to evaluate the antibacterial activities of heat-killed natural and recombinant LF-expressing probiotics against UTIs in vitro and in vivo. Firstly, using in vitro assays, we assessed the antibacterial activity of heat-killed natural and recombinant LF-expressing probiotics against uropathogenic Escherichia coli and Klebsiella pneumoniae. Among the tested probiotics, 10 heat-killed LF-expressing strains displayed superior antibacterial efficacy compared to 12 natural probiotics. Based on their potent in vitro activity, selected probiotics were formulated into three probiotic mixtures: viable probiotic mixture (LAB), heat-killed probiotic mixture (HK-LAB), and heat-killed LF-expressing probiotic mixture (HK-LAB/LF). To further evaluate the therapeutic potential of these probiotic mixtures in vivo, we established a murine model of UTIs by intraurethral administration of E. coli to 40 female C57BL/6JNarl mice on day 0. Subsequently, mice received oral gavage of placebo, LAB, HK-LAB, or HK-LAB/LF for 21 consecutive days (n = 8 per group). An additional control group (n = 8) received ampicillin treatment for 7 days. To assess protective effects against re-infection or UTI relapse, all mice were challenged with E. coli on day 22 and E. coli plus K. pneumoniae on day 25. Results from the murine UTI model demonstrated that placebo administration did not reduce bacteriuria throughout the experiment. Conversely, supplementation with ampicillin, HK-LAB/LF, HK-LAB, or LAB significantly (p < 0.05) reduced daily bacteriuria by 103 to 104-fold on days 1, 3, 5, and 14, respectively. Furthermore, all four therapeutic treatments improved the bacteriological cure rate (BCR) with varying levels of efficacy. For the 7-day treatment course, the BCR was 25% (placebo), 62.5% (ampicillin), 37.5% (LAB), 37.5% (HK-LAB), and 62.5% (HK-LAB/LF). For the 21-day treatment course, the BCR was 25% (placebo), 75% (ampicillin), 37.5% (LAB), 37.5% (HK-LAB), and 75% (HK-LAB/LF). Notably, HK-LAB and HK-LAB/LF demonstrated superior therapeutic efficacy compared to viable LAB in treating UTIs. Overall, regarding BCR, the three probiotic mixtures can provide benefits against UTI in mice, but ampicillin therapy remains the most efficient among the four treatments. Furthermore, there was no significant difference between pre- and post-challenge courses for the two instances of re-challenging uropathogens in all mice groups, as bacteriuria levels remained below 103 CFU/mL, implying that adaptive responses of mice may help reduce the risk of recurrent UTIs. In conclusion, our results provide new evidence that oral administration of heat-killed probiotic mixtures can confer significant therapeutic efficacy against UTIs in a murine model.

Abstract
Non-ketotic hyperglycaemia (NKH)-related partial seizure disorders are not uncommon in clinical practice but still deserve attention as they significantly affect neurologic outcome if unnoticed. The atypical presentation of sensorimotor symptoms can be seen in this setting, with paroxysmal character as the rule. Atypical manifestations could cause confusion and might lead to improper diagnosis and treatment. We report a case of inadequately controlled diabetes mellitus and NKH presenting as paroxysmal paraesthesia of both hands, which was misdiagnosed as diabetic neuropathy.

Abstract
We have shown previously that the TFIIIC1/TFIIIC1' fraction interacts specifically with the VA1 terminator regions to affect both termination and initiation/reinitiation of transcription by human RNA polymerase III. Here, we further purified the VA1 terminator-binding factor to apparent homogeneity and found, by peptide sequence analysis, that it belongs to the NF1 protein family. NF1 interacts specifically with the NF1-binding sites within the terminator regions of the VA1 gene and with two subunits (TFIIIC220 and TFIIIC110) of human TFIIIC2. Immunodepletion with anti-NF1 antibodies dramatically decreases transcription from the VA1 template in nuclear extract, and mutation at the NF1-binding site in the terminator region of the VA1 gene selectively affects multiple-round transcription (reinitiation of transcription) and termination. In addition, NF1 acts in conjunction with TFIIIC to promote accurate termination by RNA polymerase III on a C-tailed VA1 template.

Abstract
BACKGROUND There are no complete records on the prevalence of childhood skin diseases in Taiwan. We conducted a survey of infectious skin diseases and skin infestations among primary school children in Taitung County, which is located in southeastern Taiwan. METHODS From March 1998 through October 1998, a total of 3,029 students from four rural districts (Changbin, Yanping, Lanyu, and Dawu) and one urban area (Taitung City of Taitung County) were examined by dermatologists. Treatment and instructions for disease care were given immediately after the diagnosis of dermatoses, when appropriate. RESULTS The most common infectious skin diseases and infestations were pediculosis capitis (12.9%), verruca vulgaris (5.1%), tinea versicolor (4.4%), tinea pedis (4.1%), verruca plantaris (1.8%), and scabies (1.4%). Most skin diseases, including pediculosis capitis, scabies, verruca vulgaris, verruca plantaris, folliculitis, pyoderma, tinea pedis, and tinea versicolor, were significantly more common in rural areas than in the urban area (p < 0.05 for all). Pediculosis capitis was more common among girls (p < 0.001), but tinea pedis and tinea versicolor were more common among boys (p < 0.05). CONCLUSIONS The prevalence of most skin infections and infestations are much higher in rural Taitung County than in Taitung City. Prevention and treatment of these skin diseases should be reemphasized in the education of teachers, as well as students and their families. Adequate dermatologic training of nurses and physicians and the development of teleconsultation and teledermatology in rural areas might decrease the prevalence of these skin diseases in school children.

Abstract
Human transcription factor IIIC (hTFIIIC) is a multisubunit complex that directly recognizes promoter elements and recruits TFIIIB and RNA polymerase III. Here we describe the cDNA cloning and characterization of the 90-kDa subunit (hTFIIIC90) that is present within a DNA-binding subcomplex (TFIIIC2) of TFIIIC. hTFIIIC90 has no specific homology to any of the known yeast TFIIIC subunits. Immunodepletion and immunoprecipitation studies indicate that hTFIIIC90 is a bona fide subunit of TFIIIC2 and absolutely required for RNA polymerase III transcription. hTFIIIC90 shows interactions with the hTFIIIC220, hTFIIIC110, and hTFIIIC63 subunits of TFIIIC, the hTFIIIB90 subunit of TFIIIB, and the human RPC39 (hRPC39) and hRPC62 subunits of an initiation-specific subcomplex of RNA polymerase III. These interactions may facilitate both TFIIIB and RNA polymerase III recruitment to the preinitiation complex by TFIIIC. We show that hTFIIIC90 has an intrinsic histone acetyltransferase activity with a substrate specificity for histone H3.

Abstract
Human transcription factor IIIC (hTFIIIC) is a multisubunit complex that mediates transcription of class III genes through direct recognition of promoters (for tRNA and virus-associated RNA genes) or promoter-TFIIIA complexes (for the 5S RNA gene) and subsequent recruitment of TFIIIB and RNA polymerase III. We describe the cognate cDNA cloning and characterization of two subunits (hTFIIIC63 and hTFIIIC102) that are present within a DNA-binding subcomplex (TFIIIC2) of TFIIIC and are related in structure and function to two yeast TFIIIC subunits (yTFIIIC95 and yTFIIIC131) previously shown to interact, respectively, with the promoter (A box) and with a subunit of yeast TFIIIB. hTFIIIC63 and hTFIIIC102 show parallel in vitro interactions with the homologous human TFIIIB and RNA polymerase III components, as well as additional interactions that may facilitate both TFIIIB and RNA polymerase III recruitment. These include novel interactions of hTFIIIC63 with hTFIIIC102, with hTFIIIB90, and with hRPC62, in addition to the hTFIIIC102-hTFIIIB90 and hTFIIIB90-hRPC39 interactions that parallel the previously described interactions in yeast. As reported for yTFIIIC131, hTFIIIC102 contains acidic and basic regions, tetratricopeptide repeats (TPRs), and a helix-loop-helix domain, and mutagenesis studies have implicated the TPRs in interactions both with hTFIIIC63 and with hTFIIIB90. These observations further document conservation from yeast to human of the structure and function of the RNA polymerase III transcription machinery, but in addition, they provide new insights into the function of hTFIIIC and suggest direct involvement in recruitment of both TFIIIB and RNA polymerase III.

Abstract
In the past year we had 36 patients operated for transthoracic endoscopic sympathectomy to treat palmar hyperhidrosis. The first group composed of 17 patients receiving anesthesia with double-lumen endobronchial-tube ventilation from July-92 to April-93, and the second group composed of 19 patients receiving anesthesia with laryngeal mask ventilation from April-93 to August-93. During right lung collapse for sympathectomy, the first group patients' SaO2 (oxygen saturation) decreased from 99.65 +/- 0.62 mmHg (pre-operation) to 95.12 +/- 5.48 mmHg (at cauterization), 95.24 +/- 5.41 mmHg (5 minutes after cauterization) and resumed 99.53 +/- 0.62 mmHg after the procedure completed. During left lung collapse for left side sympathectomy, the same group patients' SaO2 decreased from 99.59 +/- 0.62 mmHg to 97.35 +/- 3.06 mmHg, 97.82 +/- 2.53 mmHg and resumed 99.65 +/- 0.49 mmHg respectively. The second group using laryngeal mask ventilation had SaO2 changes during right side sympathectomy from 99.68 +/- 0.58 mmHg (pre-cauterization) to 99.74 +/- 0.45 mmHg (when cauterization), 99.79 +/- 0.42 mmHg (5 minutes after cauterization) and resumed 99.84 +/- 0.37 mmHg after the procedure completed. During left side sympathectomy the second group patients' SaO2 changed from 99.84 +/- 0.39 mmHg to 99.42 +/- 1.50 mmHg, 99.47 +/- 1.46 mmHg and resumed 99.74 +/- 0.59 mmHg respectively. After 2-Way ANOVA with repeated measures of the SaO2 value, we could see that no matter what side operation, there were differences existed between these two groups (< 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Malonyl-coenzyme A (malonyl-CoA) decarboxylase is widely distributed in prokaryotes and eukaryotes. However, the biological function of this enzyme has not been established in any organism. To elucidate the structure and function of this enzyme, the malonyl-CoA decarboxylase gene from Saccharopolyspora erythraea (formerly Streptomyces erythreaus) was cloned and sequenced. This gene would encode a polypeptide of 417 amino acids. The deduced amino acid sequence matched the experimentally determined amino acid sequences of 25 N-terminal residues each of the enzyme and of an internal peptide obtained by proteolysis of the purified enzyme. This decarboxylase showed homology with aminoglycoside N6'-acetyltransferases of Pseudomonas aeruginosa, Serratia marcescens, and Klebsiella pneumoniae. Northern (RNA) blot analysis revealed a single transcript. The transcription initiation site was 220 bp upstream of the start codon. When expressed in Escherichia coli, the S. erythraea malonyl-CoA decarboxylase gene yielded a protein that cross-reacted with antiserum prepared against S. erythraea malonyl-CoA decarboxylase and catalyzed decarboxylation of [3-14C]malonyl-CoA to acetyl-CoA and 14CO2. The S. erythraea malonyl-CoA decarboxylase gene was disrupted by homologous recombination using an integrating vector pWHM3. The gene-disrupted transformant did not produce immunologically cross-reacting 45-kDa decarboxylase, lacked malonyl-CoA decarboxylase activity, and could not produce erythromycin. Exogenous propionate restored the ability to produce erythromycin. These results strongly suggest that the decarboxylase provides propionyl-CoA for erythromycin synthesis probably via decarboxylation of methylmalonyl-CoA derived from succinyl-CoA, and therefore the malonyl-CoA decarboxylase gene is designated eryM. The gene disrupted mutants also did not produce pigments.
