Characterization of PhPRP1, a histidine domain arabinogalactan protein from Petunia hybrida pistils

An arabinogalactan protein, PhPRP1, was purified from Petunia hybrida pistils and shown to be orthologous to TTS-1 and TTS-2 from Nicotiana tabacum and NaTTS from Nicotiana alata. Sequence comparisons among these proteins, and CaPRP1 from Capsicum annuum, reveal a conserved histidine-rich domain and two hypervariable domains. Immunoblots show that TTS-1 and PhPRP1 are also expressed in vegetative tissues of tobacco and petunia respectively. In contrast to the molecular mass heterogeneity displayed by the pistil proteins, the different isoforms found in seedlings, roots, and leaves each has a discrete size (37, 80, 160, and 200 kDa) on SDS-PAGE gels. On the basis of their chemistry, distinctive domain architecture, and the unique pattern of expression, we have named this group of proteins HD-AGPs (histidine domain-arabinogalactan proteins).

Opitz (BBB/G) syndrome: oral manifestations

We studied a new case of the G (Opitz BBB/G) syndrome in a 12-year-old boy. Several relatives had partial manifestations of the disorder. A comprehensive dental evaluation of the propositus was conducted; included is, to our knowledge, the first published cephalometric analysis of a G syndrome patient. We reviewed 139 cases of the G syndrome; 48 of them had at least one oral abnormality. These included clefting, micrognathia, ankyloglossia, and high-arched palate. Male G syndrome patients are more likely to have oral anomalies than affected females.

Gingival and cutaneous xanthomatosis associated with primary biliary cirrhosis. Report of a case

The first comprehensive case report of intraoral xanthomatosis associated with primary biliary cirrhosis is detailed. The lesions were present along the free gingival margin and labial vestibule. Crevicular fluid was noted to be tinged yellow. Generalized cutaneous eruptions were also seen. The xanthomas were attributed to the underlying hyperlipoproteinemia. Advanced progression of the hepatic disease necessitated a liver transplant. Disappearance of both oral and skin lesions were subsequently observed.

The Rieger anomaly concomitant with multiple dental, craniofacial, and somatic midline anomalies and short stature

An unusual, isolated case of the Rieger anomaly coincident with a multitude of dental, craniofacial, and systemic anomalies is described. Significant dental findings were severe enamel hypoplasia, conical and misshapen teeth, hypodontia, and impactions. Craniofacial disorders were underdevelopment of the maxilla, mandible, and anterior and posterior cranial bases, low-set ears, and a wide nasal bridge. Reported for the first time is the association of this genetic disorder with bilateral microcondyles and bilateral choanal atresia. Embryologic disturbance of the neural crest ectoderm is suspected. The patient also manifested anal atresia, scoliosis, kyphosis, and short stature. A discussion distinguishing this case report from the Rieger syndrome is presented. In addition, the possibility that the patient exhibited a previously unreported syndrome is also considered, and the term Short-F-R-A-M-E is proposed to name this new syndrome.

Detection of intracoronal resorption in an unerupted developing premolar: report of case

Identification of a resorptive lesion in an unerupted premolar is detailed in this report of a 10-year-old female. The lesion was discovered during a periodic recall examination. Early detection and treatment of this resorptive process will minimize its potentially destructive capacity. Radiographic inspection of this lesion in the preeruptive dentition should be routinely performed.

The Marcus Gunn phenomenon. Discussion and report of a case

A detailed clinical description of the Marcus Gunn phenomenon is featured. Related ophthalmologic aberrations associated with mandibular movement are briefly discussed. A report of a case of Marcus Gunn phenomenon, which was significant for a paternal history of bilateral cleft lip and palate, is presented. The general and the dental considerations in the management of this disorder are summarized. Protective eye shields are recommended for use during dental procedures.

Geographic stomatitis: review of the literature and report of five cases

Five new cases of geographic stomatitis have been presented along with data from 24 previously reported patients. For the first time, basic parameters of this disorder have been tabulated from this population. Although the earliest documented case appeared in the literature in 1955, the majority of articles has been published during the last 15 years. This increased frequency of reporting indicates a growing awareness of this rather innocuous lesion. Thus, the general practitioner is advised to become familiar with the salient features of geographic stomatitis. Prompt recognition and diagnosis of this lesion, based on the clinical findings and history, will usually mitigate the need for biopsy.

Weak compactness and control measures in the space of unbounded measures

We present a synthesis theorem for a family of locally equivalent measures defined on a ring of sets. This theorem is then used to exhibit a control measure for weakly compact sets of unbounded measures. In addition, the existence of a local control measure for locally strongly bounded vector measures is proved by means of the synthesis theorem.

On finitely additive vector measures

In this paper we extend the well-known Vitali-Hahn-Saks and Nikodým theorems for measures to finitely additive vector-valued set functions.

On the vitali-hahn-saks and nikodym theorems

We present simplified proofs of the well-known Vitali-Hahn-Saks and Nikodým theorems for measures.

Representations of weak and strong integrals in banach spaces

We establish a representation of the Gelfand-Pettis (weak) integral in terms of unconditionally convergent series. Moreover, absolute convergence of the series is a necessary and sufficient condition in order that the weak integral coincide with the Bochner integral. Two applications of the representation are given. The first is a simplified proof of the countable additivity and absolute continuity of the indefinite weak integral. The second application is to probability theory; we characterize the conditional expectation of a weakly integrable function.
